I never thought about sleeping naked until I heard about the benefits of it, like better for the body, as having clothing on speeds up the sweaty factor, and not being restricted with underwear - once I tried sleeping without underwear, I was hooked. I never realized how restricting wearing undies was, now I just wear pants or shorts and let my cock move as and when it needs to during the night. The only time I wear pants is during winter and autumn (fall), as it's too cold. Later in spring, and in summer though, it's fully naked for me. Feels great. I get why people love being nude now. It's very freeing.
