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?

Me and a guy were having a discussion in reference to puberty. A question came up in the discussion: are males born with their sperm? We went to the Sex Education Dept. of our school, and they weren't able to give us an answer, and recommended your site. So the question is, are males born with sperm, like females are born with all of their eggs?

My GF enjoys having my ejaculate on her (having me cum on her) and I was wondering if there was any way to increase the amount of ejaculate my body produces? I know I shouldn't compare myself to Porn stars, but they seem to ejaculate a lot.

I'm about to enter college and female, and, just recently, I've been attracted to a few girls. I also get aroused when I see two women having sex or kissing. I've had three boyfriends in high school, and I think I am still attracted to men. I would really like to experiment with girls to see if I am a lesbian or a bisexual. What should I do?

1) Simply I want to know (excuse me for my english, but I'm an Italian boy) how a male can be recognized as virgin. My friends say that the frenulum broke when you do for the first time...it's true?

2) I was reading the question about male virginity recognition and got a doubt. Is it possible to detect that a man is virgin of anal sex, i mean, has ever done anal sex?
