Hey diver! Welcome! First, where are you located? That is helpful for people to know. (You can be non-specific if you prefer, like Mid-Atlantic US.) Also your profile lists you as female. May want to fix that.
Finally, poly tends to focus on longer term, more emotionally connected relationships. These can come out of swinging of course, some swingers become poly, some poly folks swing and so in. But you may have better luck at finding sex only partners on swing sites. Good luck!
