How to tell if a womans really having an orgasm?

My tests

My test is whether she comes back for more. For a repeat.

Another hint is whether her nipples get hard at the moment of orgasm. And in
addition, does she exude some fluid.

I thought I knew.

But, then I caught her practicing her O face in the mirror.

This differs from women to women and once you get to know them well you'll just know.
I've known women who's stomach muscles contract, vagina's tighten around you, anal sphincter contracts, screaming in pleasure, grab your hands to place on their body, shaking, grab hold of you and take control for the last seconds etc etc etc

Everyone's individual - I've been with women who need a lot of attention to cum and others that have had full blown orgasm's without me touching them in their sensitive areas (suggestive talk and well timed and placed touches on their skin were enough to build them up and tip them over the edge)

There's no standard process, everyone is unique and once you have a proper connection of sexual connectivity both physical and mentally it doesn't take much to get satisfaction on both sides quite easily when you're truly in-sync with your partner

It matters. And frankly just about all of these can be faked.
As much as the vocal sounds are indicative, I've had women who are completely silent (which is extremely odd to me), but there are a lot of things a woman does that changes during orgasm.
There's of course tightening, but let's not kid ourselves. Unless she's been on those kegels for years religiously, you won't feel it during sex. Around your fingers, sure.
Eye dilation. This one is hard to notice, especially when so many women close their eyes or look away during sex.
A general tensing of the body that either stays and gradually loosens, or a quick loosening and change in tempo.
In fact if she's the one controlling the action, she'll very likely change pace and possibly come to a stop during orgasm while she grips muscles.
Change in breathing.
Spasms for some women. I remember one young lady who wouldn't during sex, but the moment I pulled out her body would quake.
Inability to speak. Unless they're crying out one held word. They aren't going to be able to discuss philosophy.
Change in mood. This is more after orgasm, but just like men, a woman can have a complete shift in her nature after satisfaction. Although most will keep their desire until stimulation ends. You should at least still notice "waves" between orgasms in this case, though.
Again, most of these can be faked. Honestly I don't even worry about it anymore. I don't think I've ever had a partner that didn't cum and this point I don't care if they didn't. I know every single one had fun and plenty of pleasure, regardless of orgasm.

Yes, some quite helpful and informative posts there for you.

I've always noticed both with myself and any partner I've had,
there are also variations in the intensity of orgasm. One ex enjoyed
oral but didn't climax with it, she was set over the edge by me ejaculating
inside her, and then she'd orgasm, for quite some minutes. She'd say "It's going
up and down" indicating her spinal column, if I could get her to speak at all during
it. In that case there was a lot of attraction between us, and it was quite easy to have
very strong orgasms for each of us.

People seem vastly different once you get intimate with them, and I find that helps keep it
all interesting.

Late last year I met with a friend I'd never had sex with before, and she was nervous
and surprisingly shy in bed despite being 49 and fairly experienced with guys. She climaxed
during oral, and she began throbbing in my mouth. A slight bucking of the hips with her clit
in my mouth was enough to tell me she was cumming. My hands were on her buttocks but not at
the spincter, which I'd assume was clenching with her cumming. Too shy too look at me during
sex, but her pupils had been dilated all evening in the bar, in anticipation I guess.
She fully relaxed straight after the oral and went to sleep. I had to wait until morning for us
to resume!

I'd also agree however that you can have plenty of fun without actually climaxing. It can be
quite emotionally and psychologically stimulating to do other things, roleplay, s/m etc.
