To me there is a sexual side to nudism.
The thing is to turn it into something "positive" which not everybody is defining the same way.
I admit to find it exciting to undress at a nude beach where I can look at others (women) and they look at me.
But no one shall be offended in any way by these nude encounters.
When I look at a woman, she has the right to look back of course and be sure that I am going to breach any good manner.
This together with feeling the sun on your entire body is what makes up nudism for me / us.
