My wife after 30s has mastered the blow job. I give credit to the training she has had from bfs that she has been with the last 5 years.As someone who excels in girth but not length, always nice to read this.
Can't see who you were referring to, but for some anecdotal experience...
Especially if you are on the significantly thicker side, oral sex can be very hit or miss. And borderline painful at worst.
For reference, I'm 6.1" to 6.3" girth depending on where on the shaft I measure, which is statistically very much on the large end, but there is definitely bigger out there.
Only one ex was able to give me what I would call "great" blowjobs. She had a fairly large mouth and no gag reflex to speak of. I dodged a crazy bullet in the long run, but damn could she suck cock. And she loved doing it too!
But outside of her, pretty much everyone else has had a tendency to get toothy, which is no fault of their own. Can't help the girth to mouth size ratio.
My wife is probably the 2nd best after that ex, and she has started to be able to deepthroat me though nowhere near like my ex could. But even she can get toothy at times. My best bet is if she's facing me head on. If she's coming from the side, because my cock is wider than it is "tall" as far as cross-section, it's almost certain I'll get some inadvertent teeth scraping. Doesn't absolutely ruin the blowjob or anything, just doesn't always feel the greatest.
She is now a pro cock sucker.
