Did you move right before or right after COVID happened?

It sounds like you are feeling homesick from your post. That's a normal response to having just moved to a new city where you aren't established yet with a new network of friends. Can you email or call your existing friends in your hometown and connect with them? Tell them you are feeling homesick and could use some emotional support.

I don't think you should stress out so much about the "what ifs" when it comes to dating/finding a life partner. You can't control any of that, no matter how much money and time you put into an online dating websites, or having casual hookups with other gay men.

I think the healthiest way is to just let go of your need to control your fate. None of us can control our fate. We can plan for all kinds of outcomes, but there is no guarantee those outcomes will even happen.

Oh, and you can have all the casual sex in the world you want to, but it won't give you a long-term relationship (rarely does). It just acts like a band-aid for the wounded ego. If you are truly a gay man (you wrote that you are not cisgender or heteronormative), then you don't even date women. Why call yourself bisexual?

That aside, I think the real issue here is that you are naturally feeling lonely because you moved to a new city and haven't had the opportunity to set up your new social network of friends and acquaintances. How long have you lived in your new city?
