1) In my shopping and looking for condoms, I NEVER come across a formal size chart. I have been told that I was "endowed" and that I need to look toward larger sized models, but all I ever see is "snug fit," "large," and "extra large," etc. How big is big? It would be most helpful if I knew what I was buying before I actually bought it. Do you know of the sizes of some popular condoms, or of a size chart resource?

2) I have just started sleeping with my girlfriend and I was a virgin previously. Unfortunately, a slight problem has interfered... I tried to use a condom the first time (a free one from Health Services) and it was too small on me. I only rolled up about 3/4 of the way and was *very* uncomfortable. Is there any specific brand that I could use that would be more comfortable?

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?

Dear Alice, 

I take Valtrex daily to protect me from cold sores I get on my face. I haven’t had one since I started taking it a few years ago. My partner gets cold sores on his mouth and has recently performed oral sex on me while having a cold sore. Will the daily Valtrex protect me from developing genital herpes? How will this affect me in the future?

I would like to know what you've heard about pierced clitori. I've been told that the clitoris is one of the fastest parts of the body to heal after it is pierced, and that piercing it heightens sexual pleasure. Is there any truth to these rumors?

Hi! I have a question about orgasms. I'm a female who has masturbated since her early teens and wonder if I've "overdone" it somewhat. I did it so frequently (sometimes every other day or so; sometimes I waited longer) that now that I'm in my early 20s, I find it harder to reach orgasm, and harder to have multiple orgasms (it used to come so easily to me). Have I "lost" that momentum? Can I regain it if, say, I stopped masturbating for several weeks or months?

Also, my partner stimulates me manually or with his tongue, and I haven't been able to "come" yet... is it because I've masturbated too much? Do women take longer to come? I think he gets bored doing it...
