Do any of you think that the OP will feel better if she thinks that it is her personality at "fault" rather than her body 
Not that i think that, most men are not put off a shag on account of a womans body size.
Go out regulary on a weekend night and you will soon realise that men are not choosy.
Personally though, in terms of men for a steady relationship, i think it is confidence and conversation, that makes the difference. I am struggling with my weight for the first time in my life and strickly speaking, i am obese, but i am still getting offers, by decent men (i am in a relationship, though).
The OP, as anyone is, is better off asking a friend or family member that they can trust, because there is no "generally speaking", to why a woman has a group of men flock around her.
The OP hasn't said how long she wants a man for or what for, to be able to answer her.
BLX-i am being told that my weight isn't affecting my health, so once again, it is individual.
