I enjoy the nude, and I don't give a flying fuck who sees me naked. Now for the sake of respecting other people's space I don't go naked in front of them, but people have seen me naked by accident, and I was fairly nonchalant about.
Here is a funny story. When I first lived in the dorms 4 years ago, I had an annoying female neighbor. She was a total bitch. She would constantly bang on our door in the middle of the day to ask us to be quite when we weren't making much noise in the first place. She called the Campus cops on us too and told them were were drinking when we weren't.
I got tied of her bothering us, so one day right as I got out of the shower, and had nothing but a towel rapped around my waist she knocked on our door to bitch at us some more, so I looked at my buddies and said "watch this". I dropped the towel and answered the door butt ass naked with my cock swinging in the air, and she almost shit herself. Her chin hit the floor and she was so embarrassed that she forgot what she was going to bitch about and ran back to her room.
I almost got kicked out of the dorms for it, but it was worth it. She didn't bother us again for at least 6 months.
