Mutual masturbation + cut on the hand

For last 11 years I got -ive tested and had only one partner. So I felt safe. Till that evening 2 weeks ago. I got masturbated a man with my hand. He hasn't came but for a while I could felt some small quantity of his pre-semen liquid beetween indoor parts my fingers. I dried quickly. After we've finished our fun (about 2 hours), I've discovered a little scar on the top of my hand (quite fresh, maybe from last 1-2 hours, non-bleeding, I gues I didn't got scar while masturbating this man). I often have things like that, my skin is very thin. I washed my hand with water. But I've panicked. I dont'k know the guy and I do not want to see him again. Should I worry? Was this contact pre-semen/ visible hand scar dangerous?

Mutual masturbation is a SAFE sexual practice regardless of the scar on your hand.

" Should I worry? Was this contact pre-semen/ visible hand scar dangerous?"

NO and NO

hiv is not transmitted through scars or insignifcant cuts, scrapes, etc.
