In my experience, any activity or community enjoyed by humans has a subgroup for “that thing, but also with sex”. It’s more of a reflection of what it means to be human than anything to do with the means of that expression.

Nope! :3

It's a common misconception. We're more about community than anything.

(That's not saying that sex doesn't happen between adults, but that's not what it's about, for everyone.)
