I am grinding the balls and anus, which are also gross and emit fluids, just to a different degree. Up above they mentioned women may wear underwear if they’re also wearing menstrual pads. I’m trying to find out if that is because the underwear keeps the pad in place better, or if it is as an additional layer for leakage. In the second case, if some people wear underwear as a barrier for body fluids, despite the chafing, that is what I’m trying to ascertain.
