Has anyone gone to a nudist colony and had any qualms about showing their incision?
You have the wrong idea about nudist colonies, and for that matter about nude beaches, at least the ones in Europe.
Nudist colonies are filled with ordinary people, which means they do not look anything like models. And they have all
kinds of scars.
I don't see how you could go through life and
never show your scar, anyway. You would have a very limited choice of clothing, especially in the summer, if you weren't willing to show even the very top part of your scar.
And let me tell you -- blondies and redheads, cover your eyes so I don't get accused to giving you all winkles and skin cancer -- the sun is excellent for your scar. How do I know?
Well, I am outdoors in the sun constantly, and I'm usually wearing a low tank or spaghetti top that shows almost all of my scar, which is now a nice thin, dark, flat line EXCEPT for the part right between my breasts, which doesn't get sun and is STILL reddish, wider and lumpy. I didn't care so much until I tried on a great dress that showed a little of that area and it looks way to "I just had surgery!" for a nice evening out. It's one thing to have a scar, and another to have a scar that looks as if you forgot your IV pole and you're about to bleed all over the escargot.
So I need to go to one of those nudist colonies and sunbathe!
