Everybody is going to check out everyone else! It is only natural to be curious and (literally) marvel over the diversity of the appearance of the human body. Plus, I feel as though we need to move beyond simply being embarrassed about any one part of our bodies looking a certain way. Nudists generally know this and, I think, would agree.
Do I care if someone looks at me? No. Many people express concern about being stared at or the possibility of someone having a sexual thought while looking at them, their spouse or a family member. Well people, we are not "thought police" and since there really is no way to control what people think, why worry? We are not psychic and as long as the person HAVING THOSE THOUGHTS continues to conduct themselves in a courteous manner, worrying about it is rather pointless.
What we do is infinitely more important than what we think!
I would have no problem with that, but then mine is fairly small. It is one of the benefits of being naked that everything is uncovered. I would hope that no-one would object to anyone looking at their bodies, male or female.
