Yesterday, I went to an adult theater where I masterbated myself for a few minutes while watching some porn. A few minutes later a cross dresser came over and sat next to me, she stroked my penis 3 or 4 times. Feeling umcomfortable, I left the room and went to a different room to finsh masterbating and to cum. Today I see some sort of minor cut or irritation on my penis.
What are the chances of catching any type of STD from this 2 minute encounter? Could it be irritated from me stroking it hard? Thanks in Advance.
