Habitual nudity and physical attraction.

Physical attraction to the opposite sex must be an innate feature, else we wouldn't be here.
I'm interested in what happens when the nudity taboo is taken away. Some studies have hinted at "built-in" responses. I've had people claim that sexual attraction becomes a thing of the mind and there is no physical component. I find that unlikely and of course, the possibility of human pheromones certainly complicates the issue. Perhaps even auditory stimulation plays a role.
Assuming nudists have sex, some of the people posting cast doubt, how do you become attracted? What prompts you to approach someone?
I enjoy public nudity, especially outdoors, but I don't do it enough to wear off the turn-on. Not at all sure I'd want to really.
So, what is a "natural" response?

Clothes can be far more sexually provocative than the naked body, this is why the fashion industry is so big.
