I think sometimes it boils down to how a woman sees herself.
If she doesn't think she deserves a "good guy" then she marries/dates/sleeps with ones that treat them the way they feel about themselves.
Friends of the above mentioned asshole won't warn them because they think maybe they can change the asshole's persona for the better.
And sometimes the asshole in question only shows bits and pieces of his true assholiness a little a time.
I've dated my fair share of assholes.
I think I thought I could change them.
Then I thought I could "handle" them.
Then I thought better of myself and kicked the bastards to the curb.
Self-realization and self-preservation sometimes takes awhile. And sometimes it takes a woman her whole life and many wasted years to realize it.
I hate to say it... but...
It really has fuck all to do with weight. That's only a factor. For her, and her self-esteem.
Did she ever think about NOT putting out? Seriously, close your legs honey and let them chase you instead of the other way around.
They KNOW she's an easy lay and they don't see her as a person.
I've seen this scenario time and time again while tending bar.
She's the "fail safe fuck".
If all else fails for these guys picking up a girl in the bar, they KNOW she'll put out and they can leave when they're done.
If I haven't been wined and dined then the "first date" is a "booty call"...
For me to go out and BUY my mother a vibrator is overstepping my boundaries.
I am her child. Not her sex coach or teacher. I find a line would be totally crossed. The rest of you guys can go ahead and encourage him, but I won't.
Throwing a Fantasia Party for her with a bunch of her friends and my own friends would be alright. This doesn't seem to bother me.
But for me to go out of my way and buy one for her just smacks me as rather disgusting.
She's a big girl, no matter how you look at it... she'll find a way to get one if she wants it.
HAPPY BIRTHDAY NICOLA!! 
Oh wait....
