Hi I had an encounter with a massage where I was naked under a towel the girl sat on top of me and she was also naked she simulated sex for min or so with my covered penis between her legs, I did put the tip of my finger inside her briefly but did not touch myself until I washed my hands. I am worried because I thought I saw a small wet spot on the towel where the end of my pens was. Do I need testing, am I at risk, very worried.
