Is it possible to have too much sex? I didn't see any content on nymphomania. Could you please explain it? Is it considered a disease or something? I'm beginning to think it's a bad thing having too much sex, but it's difficult to consider giving it up; just a mini vacation seems forever and this is for both of us!

My girlfriend and I have oral sex. I heard that if you blow in the vagina of a female that it could kill her. Is that true?

1) I'm 20 years old. I have spina bifida and I can walk perfectly normal but I have incontinence with my bladder. I get a lot of urinary tract infections, too. I've been with my boyfriend for 3 years now. I am kind of worried about having sex with him because I always pee myself. I was wondering what I should do to stop getting these infections so I get be comfortable during sex and not have to think that I will pee on the bed.

2) I have been friends with a guy who has spina bifida for a while now, and recently, things took a turn for the better — we are just starting a relationship. I know that he has sensation below his waist, and can get an erection, but I wondered if there is anything about how his disability will affect our sex life. I am anxious for it to be pleasing for both of us, and although we are open enough for me to ask him questions, I would like to go in prepared so to speak! Is there anything that will be able to help me in making sure that the first time for us won't be awkward, uncomfortable or downright crap?!

Sometimes I masturbate before I go to sleep at night. Usually nothing is wrong, but sometimes (and this always occurs at night, I've found) after I masturbate, a few minutes later I have to urinate. And when I do, it is usually very painful. The feeling doesn't pass either. My scrotum usually gets very tightened up, and there is painful feeling above my crotch. Usually I just sit there, drink some water until the feeling goes away. ANY idea what this is?

I was wondering about the depth of the vagina. I've read statistics that say that the average vagina is only 3 to 4 inches deep. This seems way too small to me, since the average penis is considerably longer than that. Wouldn't that mean that most penises would crash into the cervix repeatedly during intercourse? Since this obviously doesn't happen, my question is this: does the vagina actually elongate during intercourse to accommodate the entire length of the average penis?
