I've read that the head of men's penises are very sensitive, or the vein on the underside. But my boyfriend doesn't seem to be affected by it too much. In fact if it wasn't for the fact that he thrusts into my mouth when I go down on him, I would think he was completely unaffected. Could it be my technique or is he just really unresponsive or maybe even a little hardened by sex after indulging (with the same girl) in the past?

I have heard two different stories; one, that using a vibrator can do no harm, and two, that using a vibrator can do worlds of harm! I have heard that using one will desensitize the area and make sex with a real person totally unenjoyable and dissatisfying. Which theory is true?

I am an 18 year old virgin, and I have been reading about labia on your website. I realize labia come in all sorts of shapes, sizes and colors, and many other girls have posted similar concerns. My labia minora are very asymmetrical (I know, normal) and different colors (I know, also normal). The one thing that concerns me is that the left side, the much larger side, is not sensitive, in fact, I can hardly feel anything towards the end of it. It protrudes beyond my labia majora, and I don't remember it always being that way. I think it became this way when I was thirteen, and then, it was very sensitive and would hurt if I wore my jeans to tight. Is this lack of sensitivity normal? Is there any way to regain sensitivity? near the base, where it is still more protected, it is still highly sensitive. My boyfriend of 8 months and I have recently begun to explore new physical territory, and he thinks I'm beautiful, but it's hard to enjoy the closeness if I'm self conscious about my body. Do you think I should see a gynecologist?

I have a questionable ailment...I've developed a rash the day after my boyfriend and I have had sex but we've been together for 3 years, lost our virginity together and stay monogamous. So I can't see any risk in any STIs although I am planing to get a check-up soon. The rash is around my vaginal area but also near my bottom. I'm guessing I'm allergic to the latex or lube used or it could be because I shaved...should I be worried? Thank You

I am a 16 year old male, weighing in at 212lbs. I am losing weight at a decent rate, which I have heard helps your penis size. I have seen post contradicting the last statement, however from my own research; losing weight helps to increase blood flow to the penis, which in turn helps your penis "grow". On to the subject, I have what I could consider an unusually small penis. At 5 inches in length and 4 inches in girth I am not sure what size condom to get. I have been looking, for a while now, only to find nothing. To make finding the right condom harder, my girlfriend is allergic to latex. I am nervous enough about my penis size (the smallest she has had is 8 inches), but finding the right condom makes me more nervous. Thank you.

I was reading about the female anatomy on your website and you said that the clitoris was the part that would be the source of pleasure for the woman. If the most sensitive part of a woman's anatomy is on the outside, how can intercourse feel good? Also, I don't understand how intercourse would stimulate the clitoris. From the diagrams on your website, it seems to me that the clitoris is quite far from the viginal entry. How can a penis entering the virgina have any affect on the clitoris? Thank you for your response!

My girlfriend and I care about each other very much. recently we had decided to become sexually active. She has had previous partners though she was my first. She says that I satisfy her, though I have honestly told her she does not satisfy me. I told her it doesnt matter but she is very upset and I am myself bewildered. How can I not enjoy intercourse? Especially considering its a new and exciting experience?
