You can find something to wear (like GoodNites) that you can put underneath your boxers or PJs when you go to sleep. If you change in the bathroom, nobody will know. It might even be good to talk to the camp counselor about it. Maybe he could help you with ideas on where to throw them away and maybe get you a bunk close to the bathroom. Talking to a counselor about it and secretly wearing GoodNites sure beats waking up to everyone laughing! :-(
