I have slept naked since I was 16. I didn't really think about it, just seemed normal to me. Just more comfortable.
I have slept naked since I was 15, mom din not like it whilst I was living at home. Guess that she caught me aroused too often. The idea of wearing clothing to bed bed is so odd to me, I assume that everyone sleeps naked.
It's a fairly long time distant in my youth when I discarded "jamies" and slept nude. It's the norm now wherever I am, even staying over at friends who are also nudists. At the time of my conversion, though I was still living with my parents and they thought something was up with my mind. Ha, ha! No, Mum understands and is very open-minded; she actually likes to see how 30 years of cycling has put me into a shape too many people would die for. In terms of circulation, I can't see any improvement there, however body temperature will be better regulated. And yep, it's excellent for a wank or two or three or four...
I've slept naked for a few months now, before that I only wore boxers, I haven't worn proper pjs since I was about 12. Going to bed in clothes feels weird now, and it's too hot. I can only sleep when it's really cold, which can suck in summer especially when it's humid.
My husband has hyperhydrosis, which is just a long winded way to say he runs warmer than most other humans. I started sleeping in the nude out of necessity once we got married. The man can heat our little 10x13 bedroom by himself, in winter. Now, after nearly 9 years, I feel creepy wearing my long t-shirt pjs to bed. I have to be covered though or I cant sleep and with two boys who would gouge at their eyes if they saw even a hint of boob and yet just walk in in the AM hours, that's best. I somehow instinctively keep myself covered to my armpits every time, even in my sleep. If I dont have to go into town or have company, Im in those PJs all the time though. (I have 4 pair to rotate through for washing.)
Two words for this thread - DOWN BLANKETS With the layers of those things on my bed, some people might think I have a strange fetish or something. But on bare skin, fahgetaboutit. Heaven on earth is a naked snuggle on a down blanket.
I've pretty much always slept naked... Usually with the restriction of clothes I have a lot of trouble falling asleep... I love it to be extremely cold with the air on full blast and covered with lots of blankets.
