I had an intersting chat with a hispanic Uber driver last year. Somehow we got to circumscision and I learned something new. An uncircumsized male can have a very embarrassing bleed when, for example, has his first slow dance. If not circumcized, and if one doesn't regularly massage the foreskin, it often fuses to the softskin of the head, and an erection causes bleeding. Like popping the hymen.
