Nudity, IMO, is harmful to women who are (at least from my observation) more focused on beauty, and how they compare. small imperfections seem to cause large issues in their psychology. Men, we tend to fall victim to measurement comparisons. Those same issues that bothers each gender about each other, also IMO leads to comparing the other genders. Men tend to pick based on what we like to see, and vice versa. but even then it is impossible for me to think a majority or even a large minority of people would be able to have healthy relationships knowing that they can see others who don't have a flaw that their mate does. I would love for the utopian idea where all people could judge and pick their mates based on non-physical attributes, but that just isn't how we are wired. Not everyone has the same desires, but there are multiple people who desire each look. And let's be honest, how many women would be willing to get to know the guy with the small genitalia when the guy with a Huge one is right there too... we often look at it in terms of the woman, but the other way is just as difficult.
