Remember, though, in Brave New World sex was reduced to an ordinary daily function. Like brushing your teeth or taking a walk. A very benign sort of function. They took the soma and had sex. I think we are closely to that point.
Most people are obsessed with sex and I doubt they even know why, other than they feel they are supposed to be obsessed with it because the cultural Marxist driven popular media tells them it's normal. I'd wager to bet, huge swaths of the women in particular, don't even really enjoy it (free, open, promiscuous sex with multiple partners). Men probably not the case but women are still wired the same regardless of how they'd like to pretend that isn't so.
Huxley had some insights into the need to tranquilize the masses, but he had, in general, a more benign view of our rulers than they deserved, then or now.
