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?

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 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?
