I did forget to mention one thing. I go naked at home all the time with my nephew. He is more than comfortable with it. The only exception to that is in the pool. Some guys are ok with freeballing in the pool, along with diving. Not for me, nor for my nephew. Both of us wear a jock in the pool. If you want to walk normally and talk in normal octaves, gotta keep the boys in place.
Update to being naked though....its opened up a whole new line of communication between the 2 of us. Being naked, its not like either one of us has anything to hide!!! Its been so wonderful knowing he is more comfortable with himself and has a much higher level of self esteem.
