"since sex is inherently painful"
you must be doing it wrong.
its not sopost to b painfull
Afraid it is. Try orgasming without arousal.
not sure what you are trying to get at there
orgasms require arousal, at least in my Opinion
but what has all of that got to do with pain
unless u are saying that ur reacquire pain to become aroused but thats would be a personal fetish and not the hole sex world wide experience
