I'm a bisexual guy (24 years old) who had a sexual encounter with an older guy (35 years old). He said he didn't have any STD, but he had once a relationship with a HIV+ man during his lifetime. The following things happened during the date:
1) Deep kissing.
2) I received a blowjob without a condom.
3) I masturbated him until he ejaculated.
Due to the cold weather, I have some small cuts on my hand (2-4 mm), that sometimes bleed. There is a possibility that semen and/or precum made contact with these cuts. I don't know if these small cuts were bleeding at the time. Am I at risk of being infected with HIV during that encouter?
