Hello,
A couple of days ago I "made out" with a girl who I did not know. I'm concerned because I had a 1cm x .5cm open blister on my thumb. I did not touch the girl's genitals, but I did rub her arms and legs for an extended period of time. We also held hands (I held her hand with the hand which had the blister on it). Am I at risk of any kind of infection (HIV, HEP, etc.)? Thank you.
