A quote from Sci-Fi master Robert Heinlein, surprisingly still current.

Part of the philosophy of religion is to control sex. Not saying this is good or bad but ultimately it seems more fair to pair up men and women one on one so that ugly people have a chance to mate, right?

But oppression of sex can lead to enhancements and perversions of sex. Some of the strictest societies like German and Japan have some of the most extreme cases.

So the quote below is relevant to today’s culture.
