I have no idea what kind of responses I'm going to get here, but here goes, I'd really like to find out if I'm the unreasonable one here. I was brought up in a family where after toddler-hood we kept our private parts covered at home outside the bedroom and bathroom, and this is still the norm for us. My DH was brought up in a family where it's quite normal for all family members to walk about naked and this is still the norm for them. Interestingly I only have sisters and he has just a brother - I don't know if this is relevant.
This wouldn't be a problem if it was just us in the house. The problem is we have recently moved to another town and my DM now sometimes stays with us as she often works near our new house. He continues to walk around naked even when she's here (although at those times it's only really during the night, ie to the bathroom or the kitchen for night feeds). We also now have a DS and although he's not old enough to be aware of any of this I know one day he will be and I really don't want him to wander about naked - I don't want this as the norm in our house. Our family and friends (including my DGM, young nephews and nieces) come into our house without knocking (something we're both happy with) so it's only through luck that he's not been caught in the buff in the kitchen!
He thinks I'm being a silly prude and a PITA when I ask him to cover up, I think it's just respectful (to other people and yourself) to keep your private parts private. A clash of norms - who's being unreasonable and more importantly how do we sort this out?!
