Nudity wasn't common when I grew up. I never saw a completely naked woman in real life until I was a teenager.
Back then I thought this was normal, but now I know most people in my country are far more relaxed about nudity.
During my first serious relationship, we moved to a city on the opposite side of the country. Every month, we stayed at my in-laws’ house. They weren't nudists, but it was completely normal to undress in the bedroom and walk completely naked to the bathroom to take a shower, then dry off and walk completely naked to the bedroom. For me this was very strange, but in hindsight this is a far more healthy way to bring up your children than my parents did.
For them it was completely non-sexual.
For me it was different sometimes, but I got used to it.
One of the hottest things that happened was when my girlfriend felt a little ill one day. She came out of bed very late that day. I remember playing a board game with the brother of my girlfriend, her sister, and her boyfriend. Here parents were there too, but I don't remember what they were doing. Suddenly my girlfriend came downstairs wearing nothing at all. She said she wanted to take a shower but there were no clean towels. Everybody reacted like this was completely normal. No one asked why she was naked or made any comment about it. Her mom asked her questions about how she felt, and how she slept, and if it was getting worse, and if she was taking her pills, etc. And then her mom went to fetch towels. It was very weird to see her standing naked in a room with her family around. It was weird, but HOT!
