You're in a relationship with her, that's different. There's all kinds of things someone in a relationship can call me that I don't want to hear coming out of a complete strangers mouth. I'll have to read the original post again because that's what I thought they were talking about. Compliments from people you aren't intimately involved with.
I am attracted to thin women. I've dated one as recent as 2 years ago and in fact, if I was single right now I'd have no problem asking her out. She's a better dating option than a lot of fat women I know and it has absolutely nothing to do with looks.
As it is, I'm in love with a really sweet, double gorgeous woman who's better than most everyone I've ever met. She has all the looks, all the personality, none of the drama. I call her every compliment I can think of and even make up words just to compliment her with.
And yes, I call her a variety of size related names. She loves it because she knows I find her absolutely gorgeous. She told me herself she gets off on me getting off on her. If she (or anyone) had a problem with it, obviously I wouldn't say that kind of stuff.
Being called a supersized sexy goddess maybe something you don't want, but there are others who love it.
