this is true. i use to sleep naked and the wife still sleeps without panties but with a long shirt. our son comes in sometimes. one time he caught us in a 69 that was awkward. wife looked up and there he is 2 feet away and she still had it in her mouth. but he is out cold when he sleeps and when he gets up he is still sleeping. he doesnt remember anything when he does that. thank god. talk about therapy... lol. but when you have kids it is a lot harder to sleep naked.
