brad2002: Don't worry about anything, man. You are both college guys. you have dicks. You have to change clothes, piss, and shower. In other words, you are going to be naked. Be naked when you need to be naked and be clothed when you need to be clothed. No big deal. No need for a heart-to-heart conversation. Now, I recommend being discreet while masturbating. And make sure you agree on rules for having sex in the room - and stick to them. My roomies and I were naked all the time. Nobody thought or said anything about it.
