Hi,
So I recently met up with a guy I met online. I am a 24 year old male with no STD's. I was curious and wanted to masterbate with another guy. Long story short we met up and masturbated eachother. I did not ejaculate, but he ejaculated on my hand. I have no cuts on my hand and washed shortly after. I'm probably just paranoid, but what are the chances of getting an STD from that? Should I be worried and if so what STD/STI should I be worried about. I dont even know the guy and it happened so fast. Please help.
