When I was a teen, I slept in my tighty whiteys. I'd blow a load, pull the wasteband up over it, if it wasn't too far up my chest, and wipe up with the wasteband.
As a college guy, I began sleeping naked. I had a wad of cumsoaked tissues on my windowsill, next to my bed. (Cleaning ladies did the clean-up where I went to school). Or, if out of tissues, I'd just roll over in bed, and make the sheets crusty.
As an adult, I blow a load on a handy hand towel, that's wrapped around my bedpost. (It's black, and is embrodered "Cum Rag", in gold.)
Man, I was a mess as a kid. Little regard for leaving pecker tracks anywhere I felt like. My mother went trough a lot of bleach trying to get the cum stains out of my underwear. Eventually, she put tissues next to my bed, and asked me to make her life a little easier......"use the tissues will you?"
