We’re as a group too old to understand how much things have changed and try to apply our own youthful experiences upon this situation. They don’t need a dance party for sex, that’s available 24/7 at the click of a button on their cell phones. Ecstasy is the favored drug at raves among those who partake of drugs. It renders sexual response highly unlikely, among males at least. Touchy-feely it is, though, so people see that and think it’s a prelude to sex. Normally, it would be.
Maybe raves do have a side effect of distracting from sex. But still. I don’t know what modern hookup modes even are, and artistes do get bored at times while waiting for that paint to dry. Older drugs may have been more friendly to sex.
I think people are reacting to the nudity.
Oddly enough a lot of people associate nakedness with sex.
