Most Helpful Girl
I call them my boyfriends, and occasionally I will call men boys in a facetious way that mimics how I used to feel about boys when I was a girl. (Boys have cooties, ewwwww. Or I wish that boy would like me back.)
But if I am going to refer to men as a group I say men, and occasionally dude because it's Los Angeles and we just say that a lot. I might say dudebro if the guys are kinda douchey, like drunk assholes making a scene in a bar.
