Reused condom


I had anal sex in a threesome. Two guys were having sex, one came, so the other came to me and had sex with me (me as a bottom) with the same condom he used with the other guy (like three minutes after). What are the risks of contracting HIV from this situation?


Hello, and thank you for reaching out to the AIDS Vancouver Helpline.

It sounds like you have some questions in regard to the likelihood of acquiring HIV from the described situation.

From what you have described, you engaged in a threesome, but a condom that was used with another guy was used on you as well. When it comes to HIV it is important to remember that in order for transmission to be possible, there needs to be a body fluid, an activity such as unprotected anal or vaginal intercourse and a direct access for the virus to enter your bloodstream. Thus, the sexual encounter of anal intercourse with a condom is distinguished as a Low Risk activity. This is because there have been a few reports of infection attributed to this activity.

However, the reusing of a condom does heighten your risk of HIV or even acquiring a Sexually Transmitted Disease. The purpose of the condom is to stop sperm from entering the vagina or anus. Even if the condom may still look clean there is a chance it may contain semen on the outside of the condom after being removed.

If you were to pursue HIV testing it is important to remember that all test results after 90 days are distinguished as completely conclusive results unless you were to engage in further high-risk activities during that period of time.

Below I have attached a Transmission Equation Chart on the factors that are necessary for HIV Transmission:


• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection
