A quick question to all nudists

I am not a nudist. It doesn't make me comfortable. But I have always wondered how do men who practice nudism get turned on especially when surrounded by other naked people? How do other nudists react to such a thing? Is it normal? If I have offended any of you with these questions, I sincerely apologise.

EDIT: Thank you to all those who commented and gave me their perspective. It was helpful.
