The perineum is a lady's "taint meat" - the "meat" between two the orifices - 't ain't kitty, and 't ain't butt. My lesbian gf taught me that. Likewise for boys, only between balls and ****. There might be photos of Tucker Carlson "sunning" his perineum that you definitely want to avoid!

If you get sweaty, like during exercise, you might try jock itch spray like Lotrimin on your rash, after cleaning and drying it. Or gold bond powder. I use the lotrimin on my underboob. I really need to shower more.
