I'm sending you this message from the top of the Sierra Nevada mountains of California. My wife just experienced her best orgasm ever. We live by the beach, a very low altitude... so that made me wonder, although crazy, "Does altitude have any impact on sex?"

If it doesn't impact sex, it definately impacts the lube bottle as it came squirting out on it's own...

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??

My boyfriend has trouble ejaculating, usually taking a long time. I was wondering if it could have to do with his constant masturbation during most of his young life. Could it be that the problem is me? Is there a possibility that we can improve the situation?

Is it possible for nonpregnant women or women who have never been pregnant to lactate? If so, what would be the best way to stimulate in a safe, healthy way? I'd love to please my new husband with this. Are there any draw backs?

What is it that doctors are looking for in a urine test for STIs? How exactly do they test the urine for the various infections?

Thank you for your time and help.

I have been on the Nuvaring for three months now, and I am keeping it in for the four weeks then changing it because my doctor said there's no need for me to have a period. About two weeks ago I started having dark brown discharge and it has gotten more heavy, but only when I run or stand up real quick. Is this normal or should I call my doctor and find out what is going on?

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?

For the past month or so, I have not been able to enjoy sex with my boyfriend. Our sex life was great, but now I can't have an orgasm anymore. It doesn't even feel good anymore. I am able to get in the mood, but when we actually start having intercourse, it does not feel like it used to. Sometimes it will hurt a little and sometimes it won't. What's wrong with me?

I'm not wrong when I say condoms can freeze, right? I had some condoms in my car when the temperature outside was definitely below freezing. They were only out in the cold for about thirty minutes. Would it be safe to still use them? Or, should I discard the condoms and get new ones? The box says to keep it below 100-degree temperature, but doesn't say anything about keeping them above a certain temperature. Safe or not?

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”?

I would wish to know about the health implications of men using vibrators. I seem to have developed a fungus/mold. I would like to know more before a health check, approaching in complete ignorance. Thank you.
