I wanna know how you guys feel when you sleep naked and why does some doing it? I tried to sleep without anything on one night, just to try but honestly I don't feel comfy. I can't sleep for almost an hour but when I put it back on, I did sleep already. On the morning, I had a huge thought about it. Can you share your opinion?
