There are many aspects to polylove, including sex, but not solely sex. There's a bit of a distinction between "swinging" which is more about the sex and less about the relationships. And polyamory which is more about the relationships less about the sex. I mean if that makes sense? But yeah, search the interwebs and there's a site for any kind of sex you can imagine, and for all the ones you never thought of, nor perhaps wished to think of. (sorry for ending in a preposition, I may need caffeine)
