Howdy Sam, and welcome to the forum.
Unfortunately you probably won't find what you are looking for. I've seen a few people here pair off, but NEVER anybody who came here looking for a match. The only couples I've seen form are people who came here looking for good conversations.
Soooo... it seems like the best way to find what you're looking for is to jump in and participate in conversations around here.
(And even then it's not a very good chance, just a less-than-infinitesimal chance.)
