Hi there
Apologies if this has been posted before. I played with an unknown partner on the weekend and noticed when I got home that I had lost a bit of skin on my penis
Mutual masturbation is zero-risk regardless of any circumstances like skin abrasions or pre-ejaculate fluid or ejaculate fluid. HIV cannot stay active outside the body to infect another person. HIV infection can only occur inside the human body (i.e. unprotected anal sex, unprotected vaginal sex, and IV drug works). You are fine. You have no reason to get HIV testing because of this incident.
