Wanting Bisexual Male Experience for Novel

Hi all! Like the title suggests, I am wanting input from the guy bis out there! I myself am a bi girlie, and I'm writing a romance fiction that is centered around her figuring out her sexuality and the crisis that comes with that. I am trying to tackle bi erasure, biphobia, religion, and more. It's honestly just me processing my journey by writing!

However, and I know it's a touchy subject with some, but I want her to end up with a guy (after being with women dw). Only because that is my own experience, and a lot of media portraying bisexual women has them end up with a women. I feel really invalidated by myself sometimes, even though I know I shouldn't because my relationship with my partner doesn't take away from my attraction to women, and I want to tackle that feeling through my main character. However, I think want to make him bisexual and am looking for unique experiences that bisexual men experience so I don't inadvertently invalidate or misrepresent a bisexual guy (since that is not my journey). I want to do this so I can really dive into bisexuality as a whole and represent the whole spectrum.

I would love if the guys could chime in with any frustrations, concerns, repeat experiences, etc etc that you guys have faced and think would be good to include in his character. Thank you in advance! I am excited to write this book and in the process, process my bisexuality fully through my characters.
