This thread has been enlightening: http://www.lpsg.org/219784-serious-thoughts-on-father-and.html So many men have said that they felt father/son nudity was healthy and would help a man's self-esteem and the father/son relationship. I did wonder about something that no one brought up. I have a son and his father is hung. It's possible that my son will have an average size penis. Could he develop an insecurity about his penis size due to seeing his father? Could that have a negative impact on his self-esteem?
