My ex wife and i divorced several years ago, and my oldest son, now 18, chose to live with me. we have always been very comfortable around each other, being around each other in our underwear or naked is no big deal. we dont make a big show about it, its just natural for us. but now my younger son, who is 12 now, has also chosen to come and live with me now that he can decide. the other morning we were at the table eating breakfast when my older son walked into the kitchen in his boxers with some obvious morning wood. my younger son became extremely uncomfortable and left the room immediately. he has seen both of us naked or in underwear since he moved in, and it really seems to bother him. he always locks his door or the bathroom door and is not comfortable with nudity at all. what should i do? i dont want him to be uncomfortable, but i also dont want me or my older son to have to change the way we are. any advice would be appreciated.
