I know that this sounds counter-intuitive, but it isn't something you will have to worry about.  Nudism isn't a sexual thing.  Yes, you will notice other naked people, and people will notice you, but nobody cares.  There are extraordinarily fat people, skinny people, ugly people, attractive people and so on, but like I said, it isn't a sexual thing.

The best thing that you can do if this is still a worry for you, is to try it out.  Go to a nearby nude resort/club, and plan on staying for a couple of hours or more.  You will be quite surprised at how quickly you will become relaxed.

Any other guys out there want to comment on this topic?
