Re: Few Questions - Just Curious
I'm a girl so I can't answer most of your questions from experience but I have a boyfriend who talks a lot so I may be of some help.
I'm sure it's somehow physically possible to pee in the vagina, but from what I've been told by my boyfriend and other guys, it's difficult to urinate with an erection (assuming that you have an erection). So I would assume it's possible, but I certainly wouldn't allow anyone to be doing that inside me.
After ejaculation, my boyfriend has never complained of pain. The only time he says that it hurts is if he or I touch anywhere near them soon after he ejaculates, which I think is just part of the normal "cool down period" that guys have.
I'm not really sure what you're asking here, but as far as pain during ejaculation... I'm not so sure that that's normal.
I suppose it's possible to leave the penis inside the vagina and sleep for a few hours, but it would be difficult to keep it from slipping out.
Sorry if I wasn't much help. Perhaps there are some guys or other women who can help shed some more light on your questions.
