My boyfriend doesn't seem to mind, and I doubt its surprising since I started off collecting dolls (Pullips/Blythes/BJDs and then MH). He's not afraid to tell me G1s look weird though (he likes SHS best because they look long and elegant like horses should). He's very supportive! He's bought me ponies as gifts and has even lent me money so I could buy things before someone else does. He doesn't mind listening to be ramble about ponies, or looking at customs and such I link to him. He even bought himself a custom I showed him! We've watched a few FiM episodes together, and even My Little Pony the Movie. But once he realized the movie was a giant musical commercial he got really mad. XD I doubt he'll watch more G1 with me, lol.
