DLD has repeatedly stated that it is a very bad idea. You won't know if you have to take it off and massage the penis. The other problem is if you turn over in the middle of the night you can seriously hurt yourself. Some people who say they never turn in their sleep (staying on their back) are just lucky. I know it would be great to get in a good amount of time Penis Enlargement wise while you sleep, but is it worth hurting yourself. Maybe you get a curve in your dick or worse. Some may say I'm being overly cautious. To this I say: Is it really worth hurting the only penis you have. Or maybe you have a spare one in your back pocket.
