Hello doctor, I have done a greatest mistake..and i am now in fear of (STDS) sexually transmitted diseases. I Was in no help but to mastrubate after a long time,and i do not know why i had a thought of it, doing this bizzare way.I dipped my sock s in water,which was covered with my sweat.exposing my penis head into the sock s i mastrubated..My fear is whether the sweat bacteria in the socks could have Made (STds) for me.
