My fuck buddy likes water sports. One day we were at it in the shower (having sex and I was busting to have a piss and usually I pull out and let him hose himself down, but this time he said leave it there and go for it. So I filled him up with my piss. Wondering, mainly, does anyone (with a clue) have a health opinion on this, is it ok to do this (after all, urine is sterile)? and, has anyone else tried it and have suggestions, recommendations?
