Not all blondes are beautiful, but that's what these men desire. I browsed the SBs and the SDs. Most of the SDs (though broke) were more attractive than many of the SBs. Obnoxiously large breasts and a fake nose do not make women attractive.
Maybe those traits suggest that they are going to give it up.
Oh! To any SB trying out the site, make sure that you don't show you're private pics until all of your GOOD PICS are approved. Guys like variety.
Pros
connects women to generous men
Cons
generous men only want blondes with big boobs or herpes
