My best friend has AIDS and he's sexually active. He has unprotected sex with other men with HIV/AIDS. Should he use a condom instead or can does unprotected sex make no difference at all at this stage? Thank you.

I was just wondering about the difference in effectiveness between "ultra sensitive" and regular condoms. I imagine there is a greater chance of breakage with thin condoms, right? Sorry if this is a silly question, but for some reason, I thought I heard that there wasn't a significant difference.

Do you know if there is an alternative to nonoxynol-9 spermicide?? I'm allergic and was wondering if and where I could get it.

Thank you.

I believe I have a mild case of phimosis. When my penis is not erect, I can retract my foreskin all the way back to reveal the glans. However, when I have a full erection, it is impossible to retract the foreskin to that extent. I can only retract it to reveal the slit and top part of the penis. Due to this problem, I have a question about condom use. I'm still a virgin, so I have never experienced intercourse using a condom. When I read the instructions on how to use a condom, they almost always instruct you to retract the foreskin completely if you are not circumcised. Since I cannot retract the foreskin while erect, is it still possible to use a condom without retracting the foreskin, and will this complication affect slippage of the condom or sensation problems during intercourse? On a side note, why is it recommended to retract the foreskin fully before putting on the condom? Thank you in advance.

If my partner and I have been monogamous for three years (and I was a virgin before we met) and my partner tested negative for the HIV virus (twice, about two years ago, with a six-month gap between the tests) is it safe for us to use a birth control method other than a condom? That is, are there still any STDs that my partner might have without knowing it, that we should be worried about, even though nothing whatsoever has seemed wrong with either of us for three years and my partner has had several regular annual physicals in that time?

I have been seeing my boyfriend for four weeks. He has told me all about his past relationships. Is it safe to stop using condoms now?
