menstruation blood

Question

Dear Ryan,a few years ago I had an erotic contact with a lady. We did not have vaginal sex(insertion) but my penis did glide along her vagina which had menstruation blood on it. Was I at risk?

Answer

HIV transmission is known to occur during vaginal, anal, and oral sex. Any time infected fluids (vaginal, semen, blood) come into contact with your mucous membranes, transmission is possible; other modes of sexual contact are not likely to lead to infection. Unless you are engaging in vaginal, anal, or oral sex, transmission through sexual contact is very unlilkely.
