Well, the hell with that! It's your home. You get to stay, lol. If the guys want your wife one-on-one, they can host at their places, or spring for a hotel room (or a campsite, weather permitting).
Try googling "Fairbanks polyamory" or check out the dating site Feeld, which is poly-friendly. You could also try Fetlife. It's a huge international networking site for kinky people. Polyamory is not a kink, but there are lots of alternative types on Fetlife, including probably hundreds of thousands of polyamorous folks.
You don't have to "date" your wife's bfs. That's a big ask. Certainly you and your wife wouldn't want her to date any transphobes, but it would be nice if her dating partners would just respect you, and hopefully, like you as a person. If more than one man has actually told your wife that he wants you to leave your own home completely while he bangs her in YOUR bed or guest bed, well, they are barking up the wrong tree. That's just rude.
It should be your choice to leave and give your wife space, if you WANT to do that.
I am non-binary (AFAB) and my longest-term partner is technically a trans woman, AMAB (although she IDs as female). She and I both seek pansexual partners, and it took a while (years), but eventually we created the relationships of our dreams. I imagine Fairbanks is pretty conservative, as well as isolated with a low population. So you've got your work cut out for you, if you want to keep cohabiting, but still both date others!
Edit: Sorry about having to choose a binary gender when you signed up. Our admins have not responded to our request to increase the gender options, or leave that off altogether.
