That's one reason why traditionists in power usually crack down on any sort of pornography or alternate sexuality. Sex is a huge driver for human behavior. And established power structures would prefer that the only way for anyone to get sex is via compliance with the existing power structures. It's not something where the establishment is ever going to be able to perfectly control things, but if they can make it more difficult to get any sort of sexual gratification that doesn't align with their preferred social structure that gives the establishment an advantage in holding on to power.
