Questions about Ejaculation/Anal Sex

[Lydya_H]

Hi everyone, I am new to the site

Over these past few months I have been with my fiance experimenting with a few other couples, most importantly I have been having sex with a number of men at once which I really love, but of course I just want to keep trying new things and so do they, we have done a lot together but I've always been very careful and made sure they were safe and that I was too but now we're leaning towards ejaculations and all that.

For my fiance I have always let him come in my mouth or on me, I wouldn't have a problem with letting a few guys do this and actually I think it's quite exciting, it is just I have read it is dangerous to take a few at once and let sperms mix. I have only quite recently started having anal sex with them and I am not really used to it yet, but already they are asking to come in there, I've been told that just the one is OK but to let a few guys do it is a little dodgy. Is this true? Do the same rules apply for the mouth as well?

Also, I have been having anal sex regularly for a few weeks now but it still really kills me for a few minutes at first, I didn't think it'd be so bad for so long and while it's gotten better and we use lube and they prepare me beforehand I find myself just close to tears when they first do it. Some of the others have told me they were used to it after maybe four or five times and that it was pretty simple for them afterwards, I have tried it maybe 15 times. After a little while the pain goes but I'm scared of letting them do it, but they are quite considerate and only do it really slowly until I'm used to it so it isn't because they're just really going for it, how long would you all say it usually takes to get used to it? Because I'm scared I just never will and that maybe it's causing me damage although it doesn't hurt afterwards, how could I get used to it better? I have a few toys I have used and they're actually better but during actual sex it really hurts me

Is the risk of disease from anal sex really, really high? I'm sorry if it's a stupid question but everyone is telling me unprotected anal sex is ok, so far there have been occasions when condoms haven't been used but mostly I make sure of it. During oral sex I don't ask them to wear condoms anymore as I prefer it, again they tell me this is alright. They are mostly a lot older and more experienced than me and have been doing this stuff for years, obviously with their wives as well who I've talked to about this but I just wanted some unbiased opinions.

Thank you

The risk of disease from anal sex is just as high as for vaginal sex, some diseases are actually more likely to be transmitted that way. The anus has thin easily torn membranes, and when there is a tear, even a slight one, it means whatever is in there can enter your body.

There is no danger from letting semen mix, other than whatever diseases are already in the semen. Also, you should know that semen is very clever stuff. If your fiance or one of the other men comes on your pussy, you can get pregnant from that. If it drips out of your ass and onto your pussy, same thing. It might be unlikely, but it is possible.

I will steer you towards the Blank Manual (check the thread at the top of the board) where there is a lot of useful information.

 

[Lydya_H]

Is the risk with anal sex the same for the men doing it? Would it be dangerous as well for them to come into contact with someone elses semen? Can I get serious diseases orally when I swallow?

Usually when we meet up we all get checked up before and have always been OK, then we'll maybe do it three times and then get checked up again, do you think that is safe? Because I don't know anything about STD's as you could guess or how they develop. Many of them have also had operations so they cannot get a woman pregnant, does this make them safer?

Thank you for recommending that thread, Sorry for the questions, I will have to read it some more but I just had a look at a few ejaculation related links and they didn't seem to have information on these risks just techniques and experiences it seems, but the anal sex section will help me I'm sure

 

[Sarojaede]

Yes, the risk is just as great for the men if they are having anal sex with you and/or with one another. The whole point is, whether it's anal, oral, or vaginal, you are exchanging bodily fluids, which means, there is always the risk of passing along an STD if you are not using any kind of protection (such as a condom or a dental dam).

 

[Lydya_H]

I'm sorry I have not heard about a dental dam before, what is that?

We try to be really safe, can a STD just develop instantly during sex even if you have all been checked up beforehand and been passed OK?

 

[only_more_so]

No STD's don't just happen. But many of them can be spread before they can be diagnosed. These diseases aren't like the cold, where you catch them and start feeling sick in a day or two. AIDS doesn't have symptons for years, but is still contageous. Some people with Herpes never show any symptons but can still transmit the disease.

The kind of testing you talk about sounds a lot like the sort of things porn stars do. They get tested regularly, but there is still the occasional outbreak of STDs, including recently AIDS.

You should go read about STDs, and it wouldn't hurt to talk to your doctor, or OBGYN. They know all the facts and would much rather tell you about them before they happen, then treat you when you catch something.

 

[SweetErika]

The thing is, even if everyone's tested and comes out negative (BTW, a lot of times STD testing does NOT include herpes, and men aren't tested for genital warts, so "clean" may not actually mean disease/infection FREE), that doesn't assure you all of them or THEIR other partner(s) are monogamous.

Also, a lot of people SAY they're clean, when they're really not, or just haven't been tested because they don't want to know if they have something.

Bottom line, it's very unwise to trust people on this issue. You always need to assume they have something, and let that dictate your behavior. If you're willing to take some risk, use condoms for oral, vaginal and anal sex. Use dental dams if they're performing oral on you (because the type of herpes that causes cold sores can transmit from their mouth area to your genitals, even if they have no symptoms, and you'll end up with a case of genital herpes).

Safer sex with multiple people is considered risky behavior STD-wise. Anal sex is very risky behavior because diseases can pass easily.

Not using condoms with multiple people or those who may not be safe or monogamous is sheer stupidity.

I'm not saying you're stupid or you shouldn't have sex with multiple people, you just need to learn about what can happen and make good decisions based on that knowledge. If you're willing to take the risks, fine, but make sure you know what they are and protect yourself and your fiance if you want to reduce them.

Take care.

Hi,

You say you've been tested several times but aren't aware of the risks of STD's. Does the clinic you attend not offer this information? Any Genito Urinary Medicine (GUM) clinic should be providing you with all the facts, & at the very least have leaflets available to take home. The problem with getting tested & having the "all clear" is that blood borne viruses such as HIV will not always show up in a blood test until 3 months after the last time you/your partners had unprotected sex. As others have stated, are you sure the others you are having sex with are definitely being tested, & not having sex with others? Sounds like some of them are telling you whatever they think you want to hear, or aren't clued up themselves. And yes, as someone else mentioned Herpes can only be diagnosed whilst blisters are present, & they come & go, yet the virus is transmitted whether the blisters are present or not, that's how my friend caught it. And if you catch Herpes you have it for life, there is no antibiotic to get rid of it, just antibiotics that ease the pain when you get an outbreak.

Here's a link you may find helpful to read:

I dont want to be a killjoy, but at least arm yourself with the facts. I work in a hospital & STD's are on the increase. Have fun, but be safe.

 

[Lydya_H]

Thanks everyone, I will go and learn more, I never thought anal sex was so risky, or that everything was so risky So unfair we can't even have sex without maybe killing ourselves anymore.

Thanks for the advice

 

[Perfect_Trust]

Thanks for the advice

Good on you, knowledge is power (even if your a sub ). The other thing to consider is whether you want children in the future. Many infections that will NOT kill you (& those that do) can cause serious birth defects/complications to an unborn child.....

Like I said previously, I dont want to sound like a kiljoy, I took a lot of risks when I was younger & not so young, & now consider myself lucky I am clean.

 

[ChasingShadowsX]

it is just I have read it is dangerous to take a few at once and let sperms mix

I don't think "mixing" sperm is dangerous, how ever the amount of different guy's you allow to cum inside you is of course going to increese your chances of catching something on the basis of if every guy has a 10% chance of giving you an STD, 6 guys are going to increese this to 60%. You know?

But mixing two guys jizz together doesn't make a moltov cocktail. Not that I've tried it myself so I may be wrong... Just like those trees in the woods that fall when im not around.

P.S. This is a fucking hot story though, if you want to PM me some details I'd be much apreciative

 

[SubNebGuy]

It can take more than 6 weeks for the HIV virus to become detectable, so even a recent 'free and clear' HIV test doesn't mean your partner is 100% free.

You can easily give/get herpes from oral sex, even if the infected person isn't having an outbreak.

and you could have something like syphillis for years and never know unless you got tested for it.

and unless you saw the medical test saying "they are clean" you still only have the other person's word that they aren't a walking infection.

 

[SweetErika]

and unless you saw the medical test saying "they are clean" you still only have the other person's word that they aren't a walking infection.

And even if you did see the test results, you still only have their word that they didn't have sex with someone else right before or since the test.

Apart from my husband, I just assume everyone has an STD, and act accordingly. For me that means limiting my partners and using condoms every single time, no exceptions.

 

[abbey_kyle]

I am in awe that anyone still has sex without using protection anymore, much more mystified that anyone would dabble in multiple partner relationships without using protection.

I am glad you found Lit as there is lots of info here that answers all the questions you may have. For the sake of your own health, your partners' health and any future partners, please, please, please, use protection.

 

[TBKahuna123]

What concerns me the most is that almost everything in your first post is incorrect information. You've said that "They tell you"...Well whoever THEY are, they are extremely misinformed, or they are trying to get you to believe what THEY want you to. Here are the facts:

1.) Mixing semen doesn't mean anything. Having multiple partners ejactulate in you at the same time is no more risky than having the same multiple partners ejaculate in you on different occasions. The only difference is that he guys don't come into contact with anyone else's semen. That sounds like more of a homophobic hang up on their part than anything else.

2.) Anal sex IS riskier, for the reasons that only_more_so described. The anus is designed as a one way avenue and is easily torn. That is what makes it more risky than vaginal intercourse. The vagina was designed for such treatment.

3.) Anal sex doesn't get less painful with time because you get "broke in", it's usually about the skill and comunicaiton level between lovers increasing which makes it easier. Lots of lube and make them SLOW DOWN, that will help more than anything else.

4.) SweetErika said it best, having sex with multiple partners without some kind of barrier protection is stupid. I'm not judging your lifestyle choice, but this is like playing russian roulette. If you're willing to risk the bullet, then go for it, but think carefully and know ALL the facts before you do. That goes for your fiance too. If he's haivng unprotected sex with other partners, he's putting you at risk too.

During oral sex I don't ask them to wear condoms anymore as I prefer it, again they tell me this is alright. They are mostly a lot older and more experienced than me and have been doing this stuff for years, obviously with their wives as well who I've talked to about this but I just wanted some unbiased opinions.

Again, I hate to be judgemental, but this just sums up what I'm talking about. This sounds like a one-sided argument that is designed to convince you it's all cool because they don't want to wear a condom. That sounds selfish and detrimental to me. You sound very inexperienced in this sort of multiple partner environment, and that's fine, but it doesn't sound like you are being guided very well. I don't know these people, but I can't help but wonder at their motives and information. Either they themselves are poorly informed, or they are just trying to get what they want.

Either way, please, please, do some reading and KEEP asking these kind of questions. Though I know I may sound a little judgemental in this post, you will find that we try our best here to give unbiased and fact based infromation. It's important to be armed with good info so you can keep yourself safe. Once so armed, if you want to take those risks than feel free. Personally, there are too many great safe ways to experience pleasure for me to throw my dick on the crap table. If you roll the dice long enough, eventually it is going to come up snake eyes.

 

[cele2flowers]

I like all the advice given so far. You asked what a dental dam was, but I didn't notice anyone actually answer that. A dental dam is usually a piece of latex (or other barrier) placed over the entire female genital area (sorry for sounding clinical, but easier understood). You can buy these from online stores, the same that you could buy sex toys from. You can also find them in adult bookstores (though I've never looked for them there). OR you can make them out of condoms. If you want to learn how, google "dental dam."

Also, keep in mind that condoms are not 100% when it comes to STDs. Not all STDs are transferred by fluid/blood contact. Just skin to skin contact can transfer herpes and genital warts. And you can't always see these infections either!

For more information, even if you will be seeing your doctor soon, I'd check out the Center for Disease Control (CDC) website and the American Social Health Association (ASHA) website, if you really want to be informed about STDs. Then if there is something you really don't understand or want clarification on, you can ask your doctor about it. And don't be afraid to write out your questions and take them with you to your doctor visits. That's one of the many things they're there for!

 

[Lydya_H]

Thanks for the advice everyone, I'm going to have a look at talking to a doctor about all of this but a lot of my questions are really embarrassing, you know? I've had a look around the net but it's difficult finding really specific answers relating to my kind of lifestyle, so I hope I can ask them here...

Can STD's be transmitted through spit? Because a lot of the guys go down on me, it never really occurred to me I could be at risk from that but I suppose there is. Is it dangerous for a few guys to go down on me one after the other? I mean they could get stuff as well right if they're tasting each others spit?

This is probably really stupid but can I get something from letting guys just like come on me? I mean it absorb through my skin, will it? What about facials, like I know you can absorb things into your bloodstream really quickly through your eyes can't you? So that'd be really risky too? Not that it's always in my eyes but you know what I mean

Can you kind of become more resilient to anal sex? I mean, if I really become used to it with toys and everything then as long as I'm well prepared and the guys aren't too harsh then there'll be less chance of something happening? I mean, they'll be wearing condoms but I mean they could spit on it, a lot of guys like kind of licking me there as well, but I mean like reducing the chance of damaging myself and becoming more vulnerable

I'm not sure I asked either but is swallowing really dangerous? I mean I know I could get something just by oral sex but I mean one of the really serious diseases through semen, I mean that's what really asking about, you know? I know herpes etc.. is another risk but I'm worried about the more serious ones

Are older guy around their forties any more likely or unlikely to transmit disease? I mean does fertility have an effect? A lot of them have had procedures done so they can't impregnate a woman, does this make them less risky? It's really stupid as well but some of them take these tablets, I don't know what they're called but they're supposed to make their come thicker, will this alter anything?

I'm sorry if these are obvious but I'd really appreciate it, I can't go and talk like this to a doctor, you know? Thanks for telling me about dental dams, I'll have a look at getting some.

Why can't you talk to a doctor? It's not embarrassing for them. There's nothing you can say that they haven't heard a million times.

As pointed out repeatedly above, use condoms and dental dams for everything! Every time!

And here's something you should keep in mind... a lot of men will say anything to get you to let them have sex with you. If someone says "it's ok, I've had a vasectomy, you can't get an STD from me." he's either a moron, or he thinks you are.

 

[Lydya_H]

Well it'd be difficult to convince you all about the guys I am seeing but I really trust them, I know people will say I'm an idiot but I'm not just going into bars and telling groups of guys to convince me they're safe because I want to have sex with them all, they all have wives and kids and have been doing this stuff for years, but I don't want to talk about them...

Talking to your doctor might be very embarrasing, but you will get better information than you'll get from us. And much better information than you are getting from the people you have sex with. Either they are incredibly ill-informed or they should be arrested for reckless behavior.

The older guys who've had the operation are probably the ones you should be most worried about. They don't have to worry about knocking up a woman, so they probably also don't worry about wearing condoms to prevent STD. Also they have been around longer so they have had more sexual contact with different people. Think of having unprotected sex as playing Russian Roulette. They keep spinning the chambers and pulling the trigger. But if they get the bullet then so does everyone they sleep with from then on.

Yes STD's can be transmitted through spit (although not all of them). And yes a second guy going down on you can catch it from the previous guy. It would be the same as if they had kissed.

Here is a decent article on anal sex's dangers (try a google search)

That's exactly what I was thinking. If all these guys are older and more experienced, shouldn't they have the answers to all these questions?

Something seems a bit off here.

I concur.

When sex is on the line, most males will say anything to get their dick wet.

I've had a look around the net but it's difficult finding really specific answers relating to my kind of lifestyle, so I hope I can ask them here...

This is probably the best place I have found. You'll get honest answers here, and most of us are VERY well informed.

Is it dangerous for a few guys to go down on me one after the other? I mean they could get stuff as well right if they're tasting each others spit?

Yes, it is possible, but it is probably the least risky activity of all you have described. I had a cousin who actually got Chalmydia in his eyes from going down on an infected woman. Talk about looking for love int he wrong places!

This is probably really stupid but can I get something from letting guys just like come on me? I mean it absorb through my skin, will it? What about facials, like I know you can absorb things into your bloodstream really quickly through your eyes can't you? So that'd be really risky too? Not that it's always in my eyes but you know what I mean.

See the above comment. Absorbed through the skin? Probably not, but around any mucus glands(eyes, mouth, etc.), there is always a chance.

Can you kind of become more resilient to anal sex? I mean, if I really become used to it with toys and everything then as long as I'm well prepared and the guys aren't too harsh then there'll be less chance of something happening? I mean, they'll be wearing condoms but I mean they could spit on it, a lot of guys like kind of licking me there as well, but I mean like reducing the chance of damaging myself and becoming more vulnerable.

Yes, you can become more used to it, but it's really about learning pace and the mental aspect. saliva is NOT ever enough lube, regardless of what the movies may say. If you want to make anal sex easier, start with a good silicone lube. Use LOTS of lube. There's never too much lube with anal sex.

I'm not sure I asked either but is swallowing really dangerous? I mean I know I could get something just by oral sex but I mean one of the really serious diseases through semen, I mean that's what really asking about, you know? I know herpes etc.. is another risk but I'm worried about the more serious ones.

The answer is yes, you can contract an STD from swallowing just like if they came in any other orifice.

Are older guy around their forties any more likely or unlikely to transmit disease? I mean does fertility have an effect? A lot of them have had procedures done so they can't impregnate a woman, does this make them less risky? It's really stupid as well but some of them take these tablets, I don't know what they're called but they're supposed to make their come thicker, will this alter anything?

Fertility has nothing to do with disease transmission. Nothing whatsoever. Viruses aren't transmitted by the sperm, but the fluid. What you are talking about as far as the tablets is probably a zinc supplement. Again, it has no effect other than thickening the fluid.

I'm sorry if these are obvious but I'd really appreciate it, I can't go and talk like this to a doctor, you know? Thanks for telling me about dental dams, I'll have a look at getting some.

Actually I have to admit that most of your questions took me by surprise. Not supid or obvious, but surprising. The simple answer to all your question is summed up like this:

If your partner is infected, you run the risk of infection if you have unprotected contact with them. This means vaginal, oral , anal, etc. Some activities may ahve a lower percentage chance of transmitting the infection, but there is always a chance. If you have multiple partner, then that increases your risk of infection through sheer mathematics. They say that when you have sex you are having sex with every partner you partner has ever had, and that's true.

Even if you do use barrier protection, such as condoms and dental dams, there is always some risk, though it would be greatly reduced. The only way for their to be virtully no risk would be if all the parties involved were tested and clean, then had absolutely no sexual contact with anyone other than members of the group. Theoretically that would constitute one large monogamous(kinda) group, which would mean that most STI's could be avoided. Still if someone gets some other kind of infection, it could be transmitted.

I hope these answers help you out.

 

[emap]

I realy hate to say this to you, but don't trust your lovers. They are not telling you actual information, they are lying to you.

They also happen to be tossing their own hangups and wishes onto you. Most of it has been explained to you, but there is one thing nobody has pointed out. Most men hate condoms, try for all their worth to not wear them, especially when it's your boyfriend or a guy you just met and want to ride. They never have condoms with them, and they always tell you 'oh don't worry I'll pull out' They NEVER pull out, trust me on this one, friend of mine got pregnant because he said he would pull out.

One other problem with these men you trust. You have said they are all over 40 and have wives and children, yet they don't know anything about diseases.

Ummm can you say bullshit?

There is not a man alive who has lived past 20 that knows nothing about STD's, I learned a few facts on STD's when I was 10 from friends and their older sisters/brothers. I honestly have to wonder about your age since you know nothing, have they stopped doing sex ed classes?

I know, I don't know these guys, I don't know you and I don't know your fiance, but honestly, I don't want to know these men. They sound like self centered assholes that probably don't even give you an orgasm and only care if they have one.

 

[FaeryFire]

Can You get an STI from oral sex?
Yes, STIs can be transmitted during unprotected oral sex. Oral sex is a much lower risk activity than intercourse, but there's still a possibility for transmission. Not using a condom, dental dam, or other barrier puts both partners at risk. This means that performing and receiving oral sex puts you at risk.

You have increased risk of being exposed to STIs in the following situations: you have gum disease, cuts or sores, you've had recent dental work that bruised any tissue in your mouth or you have vigorously brushed or flossed.
During the 6 weeks after any type of oral or genital piercing, avoid any type of oral sexual contact.


Here's three common and potentially serious STI's, to give you an idea of what you risk every time you agree not to use a condom:

Gonorrhea
Gonorrhea is one of the most common. It is caused by the bacterium neisseria gonorrhoeae and can infect the cervix, uterus, and fallopian tubes of women and the urethra, mouth, throat, and rectum of both men and women. Because the signs of gonorrhea often go unnoticed, an individual can develop serious health complications before they recognize they are infected.
Gonorrhea can be transmitted during vaginal, anal, or oral sex and can be transmitted even if there are no signs or symptoms of infection. Since the bacteria can live for up to 4 hours outside of the body, people can also get gonorrhea from casual contact, although this is rare. The bacteria can be transmitted to different areas of the body through infected hands, or by sharing clothing such as bathing suits or using washcloths of infected individuals soon after they have used them.
Gonorrhea can be present in an individual without producing symptoms. 90% of women may have no symptoms at all and even when a woman does have symptoms, they can be confused with urinary tract infections
If left untreated, gonorrhea may cause pelvic inflammatory disease (PID) and ectopic pregnancy in women, and sterility, arthritis, and heart problems in both women and men.


Syphilis
Syphilis is the oldest recognized STI and remains a common, although serious, infection that can be debilitating and even result in death if left untreated
The syphilis bacteria are transmitted by having direct contact with a syphilis sore. These sores can be found in the external genital area, the vagina, anus, rectum, on the lips and in the mouth. You can get and spread syphilis through oral, anal, and vaginal sex or through other intimate sexual contact including kissing. You can have syphilis without knowing it and pass it on to others.
Left untreated, a syphilis infection can be fatal. In the third stage of the infection, a person may experience internal organ damage, paralysis, numbness, gradual blindness and dementia. This damage may be serious enough to cause death.

Chlamydia
It is caused by the bacteria chlamydia trachomatis and can infect the penis, vagina, cervix, anus, urethra, or eye. Because the signs of chlamydia often go unnoticed, an individual can develop serious health complications before they recognize that they are infected.
Chlamydia can be transmitted during vaginal, anal, or oral sex and can be transmitted even if there are no signs or symptoms of infection.
75% of women and 50% of men infected with chlamydia don't have symptoms. Many women only discover they have chlamydia when they have a pelvic exam or when a partner develops symptoms. Because women can have chlamydia and not have any symptoms, they can have the infection for a long time before they receive treatment. Infection can spread from the cervix to the uterus and cause pelvic inflammatory disease (PID). If PID is not treated, it can cause scarring and sterility.


The advice everyone else has given is brilliant.

Basically use a condom or a dental dam in EVERY sexual encounter.
Keep oils away from latex condoms and dams because oil breaks down the latex. Oils from foods like whipped cream can affect this too.
