I agree with you. When I am nude outdoors with people I am conscious of the breezes on my body, especially my penis. I love looking at other men and women who are nude and admiring their bodies. I see what is beautiful about people, the softness of their skin and their curves. This stirs all sorts of erotic feelings in me.
Personally nudism impacted my sexuality positively.
Public nudism helped me become less body conscious and more body confident. Inspired me to look after my body better and eat healthier as a result. Nudity with friends has brought us closer (I feel) than we would be clothed. It also helped me become more open minded exploring sexuality.
So all positive I feel.
