I'm straight myself, I generally prefer heterosexual main couples because it's the most relatable for me, and I kinda dislike when there's a lot of focus on secondary couples (whether they are heterosexual or not) just cause it's an uninteresting distraction. But I also can't really understand why the mere existence of a gay or lesbian couple/characters in the story would significantly impact your enjoyment of the work. Is it just straight up homophobia, or what?
