I absolutely don't try to show off my genitals in semi-public places. That's just rude. I'm not afraid of being naked, and do so in locker rooms and showers, but would never go out of my way to parade myself in front of others. I know I'm a lot bigger, even soft, than most men, so what would I get from flaunting it in front of other, more normal-sized guys? And since I'm not gay, the last thing I want would be to give some guy the impression that I wanted his sexual attention. In my home with shades drawn, with a partner, I'm very comfortable walking around nude all day long--OK, outside of when I'm cooking! I've been to nude beaches a few times, and felt a bit uncomfortable, but that was more because I'm not very experienced in those settings, and my mild discomfort wasn't so much about others seeing me, but just the setting overall, especially where my gazing was going to.
