Hi to all.
I'm 24, gay male. About three years ago I had a brief mutual masturbation with a guy. We touched each other's penis. He had an erection but I didn't. He touched my foreskin (I had precum) for a sec and retrieved his hand (but I'm not sure whether he accidentally touched my glans when he reached for my foreskin). I masturbated his penis with my right hand for about a minute, he didn't ejaculate. I am not sure if there was any fluild on his penis. I only have a vague memory that I didn't have any visible fluid on my right hand after touching his penis. That's it. We ended this brief encounter and said goodbye in a hurry. Minutes later when I got back to my place, I touched my penis with my right hand, the very hand that touched his penis and I didn't get my right hand washed or anything afterwards. The way I touched my penis at my place was more like adjusting the my penis's position in my shorts to make it comfortable.
My scare/concern is: am I at risk of contracting Hep B/C? (not vaccined for Hep B/C yet)
