My girlfriend (24F) of 2.5 years and I (22M) recently had a conversation during a road trip that opened us up to the idea of swinging.

TLDR: I expressed a little bit of sadness at never getting to experiment/try certain things while I was single, specifically things with other guys that explore my Bi side. She said she doesn't want me to have to feel that way, and also she never got to explore her Bi side either, and there are things she wishes she could try with girls. Swinging seems like a fun and secure solution to this.

Now, I've been interested in the idea of swinging since before we even started our relationship, but now that I've got a green light so to speak, I'm not really sure to start. We live in Michigan, but I'm not really sure what websites or apps may be the best place to start. We discussed wanting to take it nice and slow, ideally finding a couple with similar interest/hobbies and meeting them in a public place for at least 2-3 "dates" before anything remotely sexual occurs. Is this common? And are there websites/apps that support what we're looking for?

Id appreciate any and all advice, as this is pretty uncharted territory for us.
