I am a naturist. A proud one, at that. I think it's not God who wants your modesty. I think it's a flaw in our culture that men associate visible skin with sex. In the naturist community, nudity and sex are very separate. In fact, any sexual behaviour at naturist events or nudist beaches is very frowned upon. The way I see it? God gave you the body you have, in his image. So why would he want you to hide it?

Just to be clear - I am in no way judging or criticising your choice. Just... offering a different perspective. :)
