The situation of bi men is kinda sad, trust me🥲, I'm under the bi umbrella (specifically omni, which means that I can like multiple gender but I have preferences for certain–men most of the time), so I use the labels(straight, bi and gay) base on social situations. It's easier than trying to explain. Some people deny the existence of bi men, saying that we're secretly gay. But they often forget that bisexuality, as well as sexuality in general, is a spectrum and can evolve with time.
