1) It seems that I can't maintain an erection for more than a couple of minutes during intercourse. In fact, sometimes it doesn't seem to want to get up and play at all. The girlfriend is really starting to take this personally, but I know it's not her fault. Help! Are there any vitamins, diets, etc. that may help?

2) To put it very simply, I am having trouble having erections for a while now. I used to be able to. I can't have them at all, during intimate encounters or during masturbation. I get a little "hard" but cannot get completely hard. Could you please help me? Thank you!!

Here is my situation: My b/f and I had anal sex, and this was not the first time we've done it. But this time was different. After we were done I noticed there was something that kind of just popped out from my bottom. It's like a piece of your skin or muscle or something. I kept trying to push it back in, but it keeps coming back out. It doesnt cause me great pain, but just a little bit of itching sometimes. What is it? What should i do with it? Is it bad? Please let me know. Thank you.

I have found no better lubricant for masturbation than my own pre-cum. Problem is, I have plenty of it sometimes, and not nearly enough at other times (usually when I have to do it in a hurry). I would like to store some up to use for those dry times by "milking" the stuff into a small glass vial or something. However, I wonder about whether it would "spoil" or start growing bacteria, etc. If so, would that matter, since I would be using it externally on my own penis? Any ideas on how best to store it?

A woman wrote and asked you if her vagina was normal. You told her to get checked for STDs but you never answered her question. When she put her finger in her vagina, she felt bumps (she said: stalactites/stalagmites?) I, too, feel this and would like to know if this is normal. I've been to the doctor many times and have never been told that I have genital warts or herpes. Do they all have this kind of texture or am I not normal?

I am a twenty-three-year-old male who has a question about my scrotum. My scrotum seems to be tight up against my body, only sometimes does it drop a little lower. I thought that maybe my scrotum was just late in growing properly. Now I am not so sure. What should I do?

1) I had my first sexual experience on the weekend. Now I'm still bleeding. It's been about two days. Is this normal? How long does it last?

2) Recently, my boyfriend and I were fooling around and he was fingering me. He has really big hands with really long fingers and, for the first time, I felt a lot of pain followed by a lot of pleasure. After he was done, I checked my underwear and it was drenched in blood. I am assuming that my hymen was broken but I didn't think it was supposed to bleed for over two days and certainly not this much. Is this normal or is something else happening?

I took a piss and found a purple mark on my penis. I have taken a blood test, and the results are on the way to check for HIV, but I can't wait. What do you think it is? Did I just masturbate too hard? I did just yesterday.
