The risk of getting hiv varies widely depending on the type of sexual activity. Anal sex (intercourse), which involves inserting the penis into the anus, carries the highest risk of transmitting hiv if either partner is hiv-positive.   even relatively small risks can add up over time and lead to a high lifetime risk of getting.   background the human immunodeficiency virus (hiv) infectiousness of anal intercourse (ai) has not been systematically reviewed, despite its role driving hiv epidemics among men who have sex with men (msm) and its potential contribution to heterosexual spread. We assessed the per-act and per-partner hiv transmission risk from ai exposure for heterosexuals and msm and its implications for hiv. Condomless anal intercourse is associated with a high risk of hiv. Being the receptive partnerthe bottomduring condomless anal sex puts a person at a much higher risk for hiv, but its possible for either partner to get hiv. The risk of hiv transmission is greater during unprotected receptive anal intercourse (urai) than during unprotected receptive vaginal intercourse (urvi) because the rectal mucosa lacks the protective humoral immune barrier present in cervicovaginal secretions and is more susceptible to traumatic abrasions that may facilitate transmission.   people may engage in anal intercourse, which has health risks, because the anus is full of nerve endings, making it very sensitive. For some recipients of anal sex, the anus can be an erogenous.   if the hiv-positive partner is taking antiretroviral treatment and has a fully suppressed viral load (undetectable), the risk of hiv transmission through anal intercourse is zero. The partner-2 study followed 783 male couples in which the hiv-positive partner had an undetectable viral load and no condoms were used in anal intercourse. For every 10,000 instances of receptive anal intercourse with a partner who has hiv, the virus is likely to be transmitted 138 times. Hiv transmission risk through anal intercourse systematic review, meta-analysis and implications for hiv prevention. Increased risk associated with receptive intercourse (both vaginal and anal) compared with insertive intercourse. The risk estimates for the sexual transmission of hiv, per sex act, range widely, from 0.
