How private is your family about nudity?

Some families are very private, always lock their doors, are very taboo about nakedness, and others are very liberal about it. Some family members are private and others not so private. I know in my family, my mom never cared if we saw her naked, she’ll stand nude in the bathroom with the door ajar. My dad, however, is not at all revealing. Also, my brothers and I never shut the door all the way when we shower. If we need something in the bathroom while someone’s showering, we just freely walk in. Many of my friends find this really creepy/odd, but meh. It’s not like we see anything. What are the nudity standards in your home?
