The risk of HIV through unprotected anal intercourse is seen to be extremely high, as much 18 times greater than vaginal intercourse. Furthermore, the secretion of blood from damaged rectal tissues can increase the risk for the insertive "top" partner, providing the virus a route of transmission through the urethra and tissues that line the head of the penis particularly under the foreskin. In their review of 16 different high-quality studies, researchers at the Imperial College and the London School of Hygiene and Tropical Medicine concluded that the per-act risk of HIV through condomless anal sex was roughly around 1. The risk of transmission was further increased if the insertive partner was uncircumcised 0. By contrast, the per-partner risk —in which an HIV-positive person is in an exclusive relationship with an HIV-negative partner—painted a somewhat clearer picture for both the receptive and insertive partners.

I recently allowed a guy to rim me and suck me on half dozen occasions. I did not use any protection and am concerned because I often have some slight bleeding in my anal area associated with a hemorrhoid. My only contact would have been with saliva on my ass and cock. I dont know the status of this individual.
