I'm a 27 year old male. A few days ago, I met a guy who shaved my *** with a clean electric shaver and then proceeded to rim me a few minutes later. I don't believe there were any noticeable cuts. He also shaved my pubes and sucked on my penis for no more than a minute. Again, I didn't see any noticeable cuts. I did not see any blood or sores in his mouth but I do not know his hiv status for sure (he said he was std- and hiv-). Am I at risk for hiv transmission or am I just being paranoid? Please help!
