I hope this is not too much information, but I have never been a pajama person. I enjoy the freedom of being unrestricted by apparel when I am sleeping in bed. I am not a nudist as the only times that I go around naked are in the shower and in bed. I cover up with a light blanket and it just feels cooler to be naked at night, and this allows me to sleep better. I strip down, disrobe and get into my birthday suit before I climb into bed. This has nothing to do with trying to protect my sperm from overheating or with spicing up my sex life, it is just a personal preference that I have become used to over the years. Many researchers indicate that sleeping in the buff is healthier because it reduces stress, but I just like the way it feels being naked in my bed.
