We were NOT dry humping or "grinding" or anything of the sort. It is just a case of semen getting on my jeans. I was sitting in the floor in front of him and he was sitting on the couch and I was manually stimulating him. I was fully dressed with a shirt, jeans, and underwear, but he was not dressed. The closest spot that was near my vagina was on my inner thigh about 4 inches below my crotch and a spot was on my zipper. I immediately took my jeans off, washed my hands, and ran my hands over my legs and crotch area to check for wet spots and couldn't find any. Are you generally safe doing sexual activity as long as one person keeps their clothes on (assuming you are not rubbing genitals together)?
