Interesting about peeing after sex to ward off a UTI. While as a guy, UTI’s are not really concerning me your ritual reminds me of a guy I used to work with. When he was single having sex with whomever he could, he would tell me one of the things he did was drink a large amount of something prior to sex so that he would have to urinate right after. Seems he was told to do that by someone in the Army as a way to lessen the chance of catching an STD (no aids then). Something about flushing the urethra right away.
