Posting photos: cool or not cool?

I'm fairly new to nudism, and to Reddit. Still trying to build up my body confidence.

I've seen a lot of people posting their pictures on Reddit, and part of me applauds their bravery, but sometimes I doubt their intentions.

There seems to be a sexual subtext to lots of posts, or maybe that's just my incorrect interpretation?

Is posting photos a good way to promote nudism or is it counterproductive? The idea of posting a photo terrifies me but part of me thinks it would be helpful for building my confidence. But if that reflects badly on nudism or offends people then I'll save myself the trouble!
