, it located it for me. Here it is:
There was this drylander who was asked which was more significant, a literjon of water or a vast pool of water? The drylander thought a minute and then said: “The literjon is more important. No single individual could own a great pool of plain water. But a literjon you could hide under your cloak and run away with it. No one would know.”

We treat nudity, and sexuality, as things that are really so precious, we literally need to hide it from others as we fear that, exposed, everyone would attempt to get it. In a land where it’s everywhere, yet, there isn’t any need for such fear. In a way, many western cultures are already like this in relation to numerous arab cultures, for example Saudi Arabia. There, they worry seeing anything but the slits of the eyes of women for fear a man would be tempted by one. Here we’re apalled at this idea that people would believe that men should be so weak, but we do not live in Saudi Arabia; there, seemingly, they’re; and it is engrained into them in their culture. We simply have the same notion only more average; here it’s fine to see not just a woman’s face, but her hair as well, and more besides, but most tend to draw the line at some stage of skimpy clothing in public. Nudists, ofcourse, go beyond even this, although generally only in some specific settings (at the very least nudists tend to avert being naked where it’s not legal to do so).

I’d argue the issue of sexuality is pretty similar, together with the one caveat that children and pregnancy, STDs and STIs are also factors there. Regardless, my point stands; I believe that with enough conversation people will realize that the advantages to being more liberal, both clothes shrewd and sexuality shrewd, while at the same time educating ourselves more so that we prevent the blunders that makes of some such puritans, will be better for everyone.
