Unfortunately, a lot of black guys like light skin. White skin is, most of the time, considered the ideal. It’s only natural for them growing up in a society with white images everywhere they turn. A dark-skinned black woman of a heavy weight in most cases would not be desired by black men. So I think that it is not necessarily your weight they are attracted to, although it is partly, but it is your skin color, your straight hair and your fine features.
