I don't think there's anything wrong with having preferences, as long as you're not looking down on your fellow human beings. I personally don't care what people are doing romantically or sexually, assuming both parties are consenting and no abuse is involved. From what you describe, you might be overly empathetic and just imagining yourself in those situations. It sounds weird...but I don't think it's uncommon either; I'm definitely guilty of it too to a certain extent.
I will say though, I have little to no respect for the crowd that seems to think everyone needs to align with their same preferences. I've seen people in anime fandoms that will turn every established hetero pairing into a gay or lesbian one, but the second someone does the reverse, they get labelled as a homophobe or a "cis scumbag". It's part of why I swore off that repugnant cesspool of juvenile retardation that is Tumblr.
