I have what appears to be scar tissue in the form of a straight line all the way down my penis, over my testicles and ends after that. Is this unusual for a guy? I am circumcised. Is this scar tissue from that or some strange webbing from birth?

Is it true that a woman can have multiple orgasms?

1) What is the average number of sexual partners per year for undergrads?

2) Do you know how many college students are having sex? Are there any statistics? I was wondering if it is lower than a lot of people would have you believe. I feel like I'm the only one sometimes who is not having sex. Thought maybe I'd see if it was true. Thanks.

I recently had an IUD inserted. I'm not currently having sex, but wanted to be prepared as I am seeing someone who I may become sexually involved with.

My concern is I was told the IUD would need to be removed if I had sex with a partner and then changed partners later. This IUD is a 5-year IUD and the cost was quite a bit. If I have sex now and then stop for a year (or any period of time) and was to become sexually involved again with another partner, why would it need to be removed? If STDs are not an issue, does it still need to be removed?

My new girlfriend and I had sex for the first time this weekend. Later in the evening, she was curious about something... "Where is that thing going???" she asked. She mentioned that full insertion was painful and she wanted to know what I was hitting, and "how far does it go?" Being admittedly a bit rusty on my knowledge of the anatomy of the female body, I told her that I thought it went no further than the "uvula" (whatever that is), but that I would do a little research, maybe see what I could get off the Net and get back to her.
