How to get my sweetie to relax about my nudism...?

My boyfriend was never comfortable about revealing his body, and never used to disrobe completely to have sex. I have broken him of his shame, but only when it's just the two of us. I'm interested in social nudity and was recently invited to attend a local naturalist society with a good friend.

He doesn't wish to stop me from exploring nude recreation, but his views on nudity rub me the wrong way. We agree that sex and other related activity should be exclusively within a committed relationship, but he also feels that a naked body is something special and should only be exposed to one's partner.

I feel that this view is a case related to the idea of equating nudity with sexuality that plagues the US. I used to feel the same way, and I'm wondering if I can do anything to help him see things from my perspective. I feel it would help him relax about my interest in participating in social nudity, and maybe get him to join in and enjoy its liberating and empowering effects himself.
