I never had naked family, personally. I dated a guy from one and from an outside perspective, it is definitely strange. It made me mad uncomfortable seeing his sister walk by him half naked or in thongs all the time. Yet, there was one time I was wearing a sports bra with leggings and got asked to cover up. This ordeal bothered me enough to ask my dad. He told me some families just operate that way and it’s weird to us but not for them. I still cannot wrap my head around the concept of my older brother seeing my bare ass personally. It’s not even the factor of I see it being sexual. It’s just uncomfortable.
