I wanted to bring this topic over here because I wonder if there might not be a higher percentage of nude sleepers in this bunch than generally (which, apparently, is about one-third of the population), but I was surprised by the sprinklings in the thread of people who are generally uncomfortable with nude sleeping on quasi-moral grounds because their child/pet/burglar might try to jump into bed with them.
This may be ever-so-slightly off-topic, but you are my target audience for a reason. Please opine on what you sleep in and why you choose clothes/no clothes/etc.
