Yes I DoWhen I was a kid, I would always sleep in different ways as it relates to what I'd wear to bed. One night, I'd wear pajamas. The next night, I'd wear underwear. The next night might mean half of my pjs with or without underwear, and finally, I'd sleep naked. Shortly after I started doing that, which was off and on since I was about 6 or 7, any time I'd wear anything to bed, I'd wake up totally naked. I guess that sometime during the night, I'd subconsciously take them off. At the time, I shared a room with my older brother, so I kept it to a minimum to avoid any trouble.
When I was 10, I finally got my own bedroom. When bedtime arrived, I wasted no time getting naked before climbing into bed. Ever since that day, only serving in the military (Navy), being a guest at someone's house, or being very sick have been the only times that I wasn't sleeping naked, which in turn has saved my wife and I a bundle of money by not having to buy pjs every year. And once our children are old enough (and potty trained, of course), we'll let them sleep the same way if they wanted to. We'll still keep a pair or two for each of them just in case they're invited to a sleepover, but for the most part, if they wanted to sleep naked, we'd let them.
