Have always slept nude for ad long as I can remember. Don't feel comfortable with the restrictions PJs or boxers give me. My wife also always sleeps in the nude and far better for snuggling up to each other. I'm in Ireland on a motor bike tour without my wife at the moment and still sleeping naked.
Fuck clothes, unless the ambient temperature is the reason for wearing them. Whether you're awake or asleep, there's no other valid reason. Fuck society for putting a taboo on the only thing we physically are.
I've been sleeping nude for a couple of years now and I would never go back to wearing clothes to bed. Naturally this has transitioned into spending more and more time nude at home. Just before bed and in the morning when I wake up. I often find myself staying naked until I need to go out.
I was married for 18 years and it was my favorite part of being married... even if there was tension between us when we went to bed we would always wake in the morning spooning naked and that made it really hard to stay mad the second day...
