It Just Feels Good!
Why not sleep in the nude? Pajamas and nightgowns just get all twisted up around you and get so uncomfortable. I only wear something to bed if it is extremely cold (my husband the miser doesn't like to turn up the heat). I use flannel sheets year-round, and their softness against bare skin is so soothing and relaxing (especially the feel against freshly shaven legs - so lovely!) And being able to feel my partner's body against my bare back when we snuggle up in our sleep is wonderful and comforting. I think everyone should try sleeping in the nude and become more comfortable with their bodies.
