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?

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.

1) I've never bought condoms before. I'm a smart shopper — I look at things like quality and value when I buy anything — and I want to do the same with my condom purchases. But I don't know what to look for!!! And I'm not sure I'm ballsy enough to walk up to the pharmacist and ask, "Now, tell me, if your daughter were having sex, which brand of condom would you want her to use with her boyfriend?"

I want a really effective condom, that doesn't, like, smell weird or fit poorly or anything. And I don't want to whip it out and have my man laughing at it.

Who do I ask for advice on this??? Where do I go?

2) My boyfriend and I have recently decided that we will use condoms and spermicide for contraceptive purposes. We have begun experimenting with various brands/types of condoms, which has caused concern. Can you explain the various types of condoms, and/or the advantages/disadvantages of each, i.e., effectiveness, etc. Lambskin vs. latex vs. polyurethane??? We are monogamous and primarily concerned with pregnancy prevention.

I have a question that I don't think you have addressed before (hope it's not too kinky). I am interested in learning the technique for doing a prostate massage. My partner enjoys being anally stimulated and I am sure this would be a "winner" for us. I just need to know the proper way to do it.

1) Is it true that taking those Emergen-C packets or any other vitamin supplements can effect the effectiveness of your birth control pill?

2) I know antibiotics can lower the effectiveness of birth control, but can probiotics or prebiotics, such as a floral acidophilus FOS, also decrease effectiveness? I've been taking birth control pills for the past 10 years with no scares or baby bumps, and I don't want to wake up pregnant one day because I took a capsule that's supposed to be healthy! :)

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.
