Routine before going to bed

It has been some time I apply lotion or oil on my genitals and my butt crack just before going to bed at night. I love the feeling of slippery, cheeks rubbing against each other and the whole area is soft and tender when I wake up in the morning. Same with cock and balls, they all feel soft and velvety after absorbing the oil overnight. Does anyone do the same or have a similar experience?

Isn‘t that messy with normal (cotton) underwear?

With diapers - sure! Baby oil + retracted foreskin + diapers + magic wand.

@fjikvtqdb I wear nothing when I sleep. The oil (if it is good quality and very light) is absorbed within 15-20 min but I am careful not to apply too much and stain my sheets. When I dress in the morning, there is no oily residue, just very supple skin.
