My (ex)boyfriend has a sister who is a collector too, so he's pretty used to ponies. Since his sister got me into ponies, he really doesn't mind them since he has to put up with a billion of them in his house. He never bought me ponies... But he does watch Friendship is Magic, that's about it.
He also says he 'likes' My Little Pony, but he hates describing himself as a brony. :3
