In all seriousness mate, It's a gamble.
UKP serves as a broker of soughts, letting you know to a certain extent which girls are good, bad, or mediocre.
But even then there's no guarantee. Your dreamgirl may be another man's nightmare. My two favourite girls are on AW, and one has zero feedback, the other has hidden feedback. Neither has a single positive review here. But if a girl has higher than say, 70% positive reviews here, chances are she's a consistent provider.
