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.

I have a weird question. My boyfriend and I were talking and he told me that men's balls move on their own throughout the day. I did not believe him so he showed me. He got undressed and laid back on the bed and told me to lift his penis and watch real close. I did and unbelievably, his balls moved. It's like they vibrated kind of like a heart beat. It was so cool. What makes a man's balls move alone?

Should a normal man's penis become erect for a certain number of times throughout one day (without any external stimulus)? Or, do these erections occur only while a man is sleeping? I have been masturbating once every day or every other day, and I have noticed that I rarely get any of those spontaneous erections during the day at all. Plus, I have been waking up with no morning erection during the past week. Have I been masturbating too much?

My roommate and I were wondering whether or not there was a difference in sleeping with a man with an uncircumcised penis or one that has been cut? My roommate's current boyfriend is uncircumcised and she has heard horror stories about sleeping with men that have uncircumcised penises.

I am a male who experiences a lot of spontaneous erection. It's almost comical. My problem is that I model nude for art classes and have difficulty preventing or getting rid of my erection. The whole thinking about something else idea never works for me. I was wondering if you could tell me of a cream or something I could use to prevent an erection or possibly make an erection go away. I've tried the usual muscle and arthritis creams, but those don't work. I can still get an erection anyway. Is there something that numbs for a period of a few hours that I could use? I thought of using some desensitizing creams you can find at adult stores, but didn't bother trying them because I figured they're designed to help you keep your erection, not lose it. It would be very helpful if you could help me out.

My friend had to have both of his testicles removed because of Testicular Torsion... will he be able to get an erection now?? What are the testicles for, anyway??

While reading some of your responses to female arousal, you say that the clitoris is as sensitive as the penis. Why is it then that when I touch mine, I get only a little pleasure, if any? Yes, I know where the clitoris is, so that's not the problem. What's wrong with me?

My fiance and I frequently enjoy anal sex. We no longer use condoms with each other during vaginal sex or anal sex. He enjoys ejaculating in me during anal sex and I don't mind it. Immediately afterwards I go to the bathroom and get out his cum, but sometimes it takes awhile for it to all come out. I'm wondering if this is OK to do or if it is harmful to my body because I do enjoy it and would like to continue. I just don't know anyone else who does this and wonder if it could harm me in any way. I've been wondering so much about it lately that I don't want to have anal sex anymore because I'm worried.

I enjoy performing cunnilingus on my girlfriend, and every so often, I get a sore throat. My question is, is it all right to perform cunnilingus on my girlfriend if I have a sore throat? Or is there a chance that whatever causing my throat discomfort could cause her trouble as well? Can the “giver” of oral sex pass along sore throat germs to the “receiver”?
