today when I went to clean it, and i noticed the tip of the f******n is all red when I pull it back. when I just look at the whole thing, the skin is all puffy, and I'm having issues pulling the skin back. I had an erection lasting about 3 hours, and was jacking off most of the 3-3 and a half hours. I've also been having issues reaching climax for a while. Is this just because I've masturbated for so long, or did I somehow do serious damage?
