Back in the days when I was in high school, I was a wrestler, once I put some balm on my shoulder and in about 5 minutes my shoulder was on fire. I had washed my hands because it was making my hands uncomfortable, then my hands were fine. Before I went to the shower to get the shit off my shoulder, I took a piss, no problem, until I was showering. That shit almost burned my dick off. It lasted days. sweat on my crotch fucken burned. I remember telling my mother that my stomach hurt so that I did have to go to school. Hell, although I couldn’t wash that shit off my shoulder either, That wasn’t my problem anymore, it was charred weenie, fucking well done. My hands were clean when I took the piss, in other words, all that shit lingers.
