My boyfriend recently came down to visit. I was on my third day of my period. I was wearing a pad, underwear, and shorts and he was only wearing these tight boxers. We ended up dry humping. He came but inside his boxers. I could feel a little wetness, from him, near the crease besides my thigh. There wasn't a visible amount on me, I could only feel some wetness. Also I gave him a hand job and after he came I immediately washed my hands. Would that cause a problem? I'm a bit of a worrier so i'm freaking out right now.
