The only cool male in this show (Braeburn) hardly talked to her and literally disappeared, and the only other cool stall (Shining Armor, which I dislike =P) is a moron already married.
I really hate the popular choices for her canonwise;
The BG ponies paired with her are also “shared”, and hardly have a personality;
OCs showed up to be far cooler than whatever Hasbro offered us (in fact, I think they like to emphasize that males are jerks).
OCs view Fluttershy as a feminine creature rather than a skinny moron (yes, Dumbbell faggot, I’m looking at you).
OCs paired with Fluttershy are usually male - yes, I prefer straight couples, but ain’t no homophobic. The only mare for Fluttershy is Rarity.
*NOTE: “stall” is from “stallion” and is the pony version of “guy”
