It is assumed that the reason that plus-size women are often BFFs with gay men is that they can't get affection from other men, or even get dates, and that gay men pity them and are using them, giving nothing back. Well, I am one of these women, and those assumptions just don't fit.
For me women were a safe way to explore the world, offering relationships uncomplicated by sex. They were my "in" to relationships, teaching me how to build trust and make real connections with the objects of my affection. There should be a better name for this kind of friendship.
