Has anyone any experience of this?
I've come to the conclusion this must be mine.
I can't climax from penetrative sex - either from grinding or trying to use my fingers.
I have no problem doing using fingers or bullet vibrator while not having (penetrative) sex.
If a man tries to use his fingers or mouth to make me climax, I can't (or at least haven't to date). I think they're possibly a bit lost because there's no visible clitoris to rub or whatever.
(Though some have also just been inexperienced/lazy/selfish/disinterested).
