You could become several gay men

The good news is that there is another single gay man out there for you. Several hundred to thousands depending on your area. Single straight men don't have that going for them so you have the advantage here.

Go through all your hobbies. Find every meetup related to them within an hour of your location. Attend them. Have fun doing what you are doing. Maybe you meet someone, maybe you don't, maybe you meet people that help you meet people. Either way you are out and doing the things you like and that's better for your mental health. It's win-win.

I'm tired of being a single bi man. You anywhere near Minneapolis and want to go on a date?
