Yes, but it takes a little background to explain. Years ago, I got a delivery job at a high-end grocery. The dress code included black dress pants. I started in the height of the July heat doing physical work outdoors wearing long pants. Right away, I developed diaper rash between the cheeks, which was... unpleasant. Each day, I'd come home and get in the shower to wash my crack, and it was amazing. It felt so good, my knees would buckle, and a couple times my vision faded out. Far better than any orgasm.

It only went on until the rash cleared, under two weeks.
