To the naysayers: Same length rod has been up my cock all the way into my bladder, tied in place with a piercing in my dick head, to bump into a toy in my ass-cunt and I never went to a hospital. Instead, I have completely different feeling orgasms. See my video. Just don't force it. And, the inside of your piss hole is not as clean as you wish, I've even used anal mucus to lube it sometimes. After very deep and thorough enemas, of course.
