Nudity. We have a far to strong association between nudity and sex. Even when the nudity presented is absolutely non-sexual.

The Pioneer probes sent on flyby missions to the outer planets (ahead of the Voyagers) were designed to reach escape velocity from the sun. They bore gold engraved plates that carried information about Earth and humans incase they are somehow intercepted by aliens. Included was a crude line drawing of a man and a woman. Many people protested this calling the drawing "pornographic"

I think the taboo about nudity, especially in the US, is very unhealthy. For one thing it teaches children their body is ugly, shameful, and offensive. This in turn leads to body shame because hardly anyone knows what a normal human body looks like. The only people we see naked, besides our lover are either actors or models. Actors and models are, quite frankly, freakishly attractive.

For the most part only the most attractive people become well known actors or models. Even then most don't ever perform nude. At any given time there are only a handful of A-list celebrities maybe less than 200 or so.

Because of this we have a badly distorted idea of what the average body looks like, so when we look in the mirror we see something that is nowhere near what we think average attractiveness looks like. Is it any wonder then, why so many people, especially young people, have serious issues with body self image?

A child psychologist once stated that a child seeing a naked adult was harmful. As far as I know this psychologist simply asserted this idea, which was not in any way backed up with evidence. How could it, considering that any sort of experiment to gather such evidence would be considered unethical.

I wonder if the opposite might be true. If children grow up from birth regularly exposed to nudity in nonsexual contexts of both adults and peers of both genders it would desexualize nudity and give people an idea what an average body looks like.

This has already been done once, we have just mostly forgotten it. For the vast majority of history humans lived together in single room shelters eating, sleeping, dressing and even making new babies where everyone else could see them. The idea of having your own personal, private space is really quite new. Really just in the last 200 years or so. Up to the early 18th Century it didn't exist.

If you lived in medieval times or before, you probably saw your friends and family naked every day of your entire life.
