Is it possible to get an std from masturbation or any none sex related cause? I ask because I have been getting some form of sores on my penis, yet I am very much still a virgin, and I now get a bizarre white substance from my sores, and I know for a fact that it is not semen, as well, the sores hurt if water touches it, or anything else, and I believe I have sores under my foreskin, it s quite excruciating when I try to pull the foreskin back to clean it.
