      Don’t humans start out with them before they then later develop into the anus and genitals if I’m remembering my random Internet rabbit hole searches correctly

        Probably. I know everyone starts off as girls before some continue on as guys. Which is why guys have nipples and that line on their scrotum and taint.

        Not so sure about the earlier developments though.
