I'm weird about it. First of all, I like to sleep on my side. And I always face the closest wall. It just feels cozy to me I tuck one hand under my pillow and cuddle with it~

Sometimes I sleep in a fetal position and sometimes I sleep with my legs stretched out. It really just depends which feels more comfortable that night.

As far as nudity goes, the only times I sleep nude are the times I don't remember taking my clothes off and I just wake up that way the next morning. I always like going to bed in pajamas and a t-shirt/hoodie. Without pants my junk just feels out of control and it's pretty uncomfortable. Plus I like being really warm in bed.
