If you would need to describe the free use fetish to someone, how would you do it?

An exploration of fictional worlds in which sex is seen as just a normal part of everyday life, being of no more importance or consequence than other common social activities, like going to work, shaking hands, saying hello, etc.

In freeuse worlds/societies, the very idea of saying no to sex is absent - it would be like saying no to being part of society completely.

Though it is a spectrum fetish. Just like not everyone into BDSM is into chains - some prefer silk scarves…
