so today me and my friend got a little frisky and he pulled out his penis and was looking up while doing it.. i’m looking at it and it’s bleeding so I ask him why. it wasn’t in the hole or anything. it was the circumstance where the tip ends to get to the shaft.. so basically it was on the shaft but closer to the mushroom part of the penis in the crease.. it was just a small line of blood like it had been cut or something. I asked him had he been jacking off or something and he said maybe. I can tell he was embarrassed but I did not make him feel shame whatsoever I played it off I understand things happen. I dealt with a guy that skin would pull if it was to much friction.. but blood? I always give him head so makes me not want to do that.. we do use protection. btw. but what could this be?
