I'm not a huge fan of her but,
I understand you're comparing her to girls with smaller boobs, however - there are not many women with REAL boobs the size of hers that are not a bit droopy, and some guys like girls with big (real)boobs.
yea shes attractive, but oogling over her isn't going to get anyone anywhere. sorry to put this the hard way, but she wont talk to you, date you, sleep with you, be a part of your life. so why build a crush type obsession.
