Public Nudity

What do you think of public nudity? If there wasn't a high probability of an increase in sexual assault and harassment, I would be all for public nudity. I mean, why are we so modest and sometimes disgusted by the outer human body? Most everyone will see breasts, butts and both sets of genitals during their lives. You think it's gross to show them in public? Why? We all have genitals, one form or another. It's normal. Why are they such a private thing we're modest to show and disgusted to see? I mean, unless a girl or guy was trying to be inappropriately sexual with them, what's the big deal? As for hygiene problems, people could carry around their own towels to sit on, to keep any liquids, illnesses, bacteria, etc to themselves, rather than leaving them wherever they sit.
