Civilized society tries to hide this fact - and it does a pretty remarkable job considering the sheer force it's up against - but human beings and living organisms in general are pervasively sexual, by design. It's our prime directive. And it's stupidly simple, but covering up our bodies actually does provide some measure of distraction from the thing our bodies are meant to do above all else. Nudists therefore have - and will ALWAYS have - a problem normalizing nudity, without it being taken over by simple-minded flesh bags who just want to fuck. (Especially online, where it's harder to control the flow of media and police people's behaviors and intentions). And it's going to be counterintuitively worse, the more restrictive of sexual expression our society is. (And, in spite of our immutable instincts, society is pretty damned restrictive right now). This is natural law, and predictable human behavior.
We can go a lot of different directions from this point, but we're not going to get anywhere without acknowledging that this is where we start. Furthermore, any social movement that seeks to metaphorically (one hopes that is all) castrate mankind's sexuality is going to run up against considerable obstacle - as it should. I'm not sure there is any reward that is worth sacrificing sex on a community-wide level. If nothing else, the very evolutionary process of natural selection will ensure its extinction within a single generation. Feel free to disregard this advice at your own peril.
Like, I can't get over the cosmic joke that is the shame and stigma we place around what is simply nature's way of making us feel good so we'll be incentivized to propagate the species, which is the one thing ensuring our continued existence beyond the temporary survival of any single organism's lifespan. Yeah, it's really important; so I understand the meaning and significance and ritual we attach to it, but why so much judgment and loathing (of both the self and others)? And what's with the absolute contradiction whereby religion deifies procreation ("be fruitful and multiply" crossed with the utter abolition of contraceptive methods and practices) while simultaneously demonizing the recreation that accompanies it? It's fundamentally Puritanical. Why is suffering divine and pleasure evil? Why must we hate what we undeniably are?
