The main character in a action/sci-fi story I'm working on is a bisexual male. Now, to me at least, it seems you cannot have a bisexual character without him/her being romantically linked to a member of the same sex OR cheating on a member of the opposite sex (I'm looking at that girl from Dodgeball for my latter observation). Both of those charactristics are not where I want to take this character. His romantic relationships are not a big factor in the story (no character's relationships are, mostly because I suck at writing romance) and as of yet, I have yet to create a character I would like to pair with him and is kinda a prude when compared to other characters. He just looks at boys as much as he looks at girls. My question is, does his sexuality need to be mentioned at all? Or should I drop subtle hints, but never out-right confirm that he is? I'll be damned if I ever write a "strong [insert minority here] character". I always write my characters as "just happening to be [insert minority here]" and this character will be bi in my mind, whether or not I say so in the story.
