[Question #4178] Heterosexual anal sex

32 months ago
Hi there. I have a new partner. He is heterosexual, not a drug user and I do not believe promiscuous. I am a woman who is always careful. We did use protection but the condom broke during anal sex and I was fully exposed to his semen. He said he was tested 3 months ago for STDs and hadn't been with anyone since. Of course I can't know any of that fore sure. So my question is, how much is the risk for the receptive partner if he were to have HIV? We are in Canada I should mention, which I know helps as rates are lower in industrialized countries. Thanks so much!

Welcome to our forum.  The exposure you describe sounds quite low risk.  From a theoretical perspective however, if your partner had untreated HIV and you were engaged in receptive rectal intercourse with him, the risk for you acquiring HIV is about 1 in 100-200.  This is in contract to the risk for acquiring HIV from vaginal sex in which the risk for infection is about 10 times lower, ranging from 1 in 1000 encounters to 1 in 2000.

I hope this information is helpful to you. EWH

Thanks Dr. Hook. I will ask to see his results to put my mind at ease, if he did indeed get tested. If he has not, I will ask him to be.  Is his risk high for HIV from being a top with women for anal? I do know he doesn't do drugs and has never been with a man. Thanks

I think it is reasonable to ask him to test.  When you do, I suggest that also offer to be tested for other STI and that you offer to be tested as well so your request does not sound as though you do not trust him but that you only want to be sure.   Being a top for insertive rectal intercourse is higher risk than for insertive vaginal but lower than for receptive rectal (i.e. being a bottom) - somewhere between 1 in 200 and 1 in 1000.  EWH

Thanks again. He will probably tell me to walk when I ask. So for myself, do they do anal swabs for STIs (sorry... new the anap part of things.) Thanks again

Dr. Hook is traveling without access to the forum.

Anal swabs are often done during STI testing, but many doctors or clinics do not do them unless the patient reveals the details of the sexual exposure. Tell your doctor and you can then expect an anal swab for gonorrhea/chlamydia testing.

Sorry for the delay in this reply.

We are beyond the normal forum limits, i.e. two follow-up questions and replies, so that concludes this thread. Dr. Hook and I hope the disucssion has been helpful.
