I am a twenty-one-year-old virgin who has just recently started seeing a girl very seriously. I am frustrated at how my body reacts to the slightest physical stimulus. Holding hands, talking about physical affection, even thinking about kissing gives me an erection. I am not thinking about sex, and we are not going to have sex until we are married, but I can't believe how frequent these erections are. I know it's common for guys my age to have erections, but just being with a girl I care about gives me one, and it's not easy to hide, and I don't want her to think the wrong thing. I used to masturbate and view pornography a lot but I finally stopped because I didn't agree with it. I stopped about the same time I met her. Do you think that my past is causing my body to want something I'm not going to give it?

1) I have trouble getting an erection after ejaculating. I wait 10-20 minutes, but it doesn't get too hard. It sometimes annoys my girlfriend. Is there anything I can do besides waiting till the next day?

2) Are there methods through which men can regain their erection quickly following orgasm?

3) I'm not really sure how to ask this question, so I'll try my best. I know that there is a certain period of time in which a man has to "recharge" after he cums. And I was wondering what the time period is before a man is "fully loaded" again, if there is any at all. Sincerely,

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...

This is sort of embarrassing, and you touched on it in a previous message, but... how do you decrease penis size? I'm serious. Is there some sort of surgery? I ask because my girlfriend says mine is too large, and it sometimes hurts her. Please answer.

I have a question concerning veins on the penis. For a long time now, I have had a vein on my penis which is quite visible. The other day I noticed another vein on my penis that was becoming more noticeable. I know that there are no physical problems with having visible veins on my penis, but I don't like it. What has caused these veins to become more visible and how do I cover them up? I j/o frequently. I know this is a cosmetic problem, but it's an important problem to me. Thanks for your time.

I have (with much distress) that sometimes when I am having intercourse with my girlfriend, at the point of climax, my right testicle will "ride up" out of the scrotum into my body. I can feel it wedged up there and I usually can push it out back into the scrotum after withdrawal. Is this something I should be worried about?!!! I was born with normally descended testicles, and I haven't been kicked in the groin or anything and it only happens sometimes, not every time. It doesn't hurt when it rides up, but it is uncomfortable and feels strange. It is only the right one, never the left that does this.

1) What is the percentage of people who develop enough antibodies for HIV virus in the first three months after exposure? Does the length of window period depend only on the response of one's immune system or also on the amount of infectious fluid that was transferred during sex?

2) My question is about AIDS/HIV: I had a sexual affair that lasted two-and-a-half months, and, unfortunately, I was not using condoms. I happen to know nothing about my partner's previous sex life. I know that, for a test to show something, you must wait for six to nine months. I would like to know whether, provided that I am infected, I will experience any symptoms in this six to nine month period? Is it possible to have the virus and not have any symptoms or indications all this time? Right now, I am a graduate student and I am experiencing anxiety, fatigue, sleepiness, weight loss (three to five pounds in the last two months). Are these related to the disease, or is it just in my mind?
