About 4 weeks ago, went to a massage place and had a hand job from a women, no sex whatsoever, no oral sex(mouth or anything related), only thing was that i was naked on my backside and the massage lady was naked too, has she was massaging me felt like her vagina was rubbing around my buttocks close to buttcrack area, i know that certain stds can be cause by skin to skin contact with fluids, so was wondering if her vaginal fluid(felt like something wet touch my butt’s skin not sure whether or not it was fluids or sweat) can pass through my butt’s skin and i can get an std somehow, or is it not possible ?
