I read fanfics, but I don't ship stuff like people would usually do.
I don't have OTPs, everything is fine as long as the characters are realistic together, and there is enough connection in the canon or created in the fic. I like fluff, smut, pwp, depending on my mood, but I usually end up with the former two as fluff gets way more lovey dovey than sensual. I tend to interpret romantic content as deep friendship or if its heavily shippy, as bad writing. (It's not necessarily actually bad, but because the emotional part feels so alien, in my head it gets filed under 'exaggeration')...
I'd go for fandoms that are either poly af like Sense8, or where the romance is kept very subtle like in Star Trek. I don't like reading about jealousy, s/D dynamics, cheating dramas, the out of the blue demonisation on exes (or the canon love interest) in order to solidify the main pair. Those are not just alien but also creepy.
The fetishised grey romanticism is also a cringe worthy thing writers like to use to emphasise the intensity and importance of romantic feelings. (I have nothing against grey romantic people, I just don't like when it's implied that aros should be fixed and one will turn into a whole different person once Their True Love walks through the door. It's the same nonsense as when bi/pan people are suddenly 100% gay or 100% straight cos They Found Love. Dafaq?!)
And then there are the damn soulmate AUs with the connecting red strings, count down tattoos, colour blindness, and the rest. I'm not sure if these were meant for lovesick teenagers or adult alloromantics like them as well. Anyway, not really my cup of tea, I never really understood it, its just eww or meh depending on how it's done.
Yeah, it's a mine field. I quite often tend to look for the smut or poly themes. Half of the aromantic and QPR tag is written by alloromantic aces, so it usually gives me the exact opposite of what I'm looking for.
