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?

I saw Ben Wa balls in a sex store and it says they improve sexual pleasure by improving vaginal tone and can even be worn during sex — is this true? Do they work and are they pleasurable?

My wife and I had our first child last July. Until about 3 months ago, she was unable to reach orgasm at all. Of late, she has very small one's, but they don't seem to be getting much better. Prior to having the baby, she had strong, very quick (3-5 minutes) orgasms 90% of the time. I know the stress of being at work rather than home with the baby could play a part in this. Is this common and is there a way to mitigate the problem? 

I am a well-adjusted late twenties male with a steady girlfriend. Lately, I have been increasingly fantasizing about various types of anal penetration. I have discovered that during masturbation, this brings me very intense pain/pleasure. Even though I think it may be satisfying to experiment with a vibrator or other objects inserted by my girlfriend, I find myself drawn toward trying the real thing (i.e., having anal sex with a penis). The problem is, I definitely do not consider myself homosexual and, in fact, the thought of the actual act with another man actually repulses me. Am I trying to have the real thing without going through a bisexual experiment or what?

I currently use NuvaRing for contraception. Because the ring slowly emits hormones into the body via the vagina, my partner and I are wondering whether he will have an unhealthy amount of contact with these hormones during oral sex. Thanks.

I am curious about double penetration (two penises in one vagina). Because of the increased friction, even if both men are wearing condoms, is there more of a risk that the condoms would break?

Is it true that a woman's sex drive is at its peak when she reaches 30? I can vouch for the fact that at 32, I think about sex more than I ever have in my lifetime.

1) What is the best way to learn how to prolong male orgasm when having intercourse? It seems that I might get thirty seconds of penetration before I blow my top. I'd like it if I could enjoy the situation and add to my partner's pleasure by helping her orgasm.

2) I just wrote asking about how I might prolong my orgasm so that my girlfriend might be able to reach hers. I've read through your archives extensively, so I've seen all the "orgasm is personal and shouldn't be concentrated on" so I've seen that and whatever. I just want one issue discussed: how to prolong MYSELF to please her. I'm looking for answers such as: exercises, workouts, diets, surgery (jk). Please help me please her.
