Most Helpful Girl
Get to know her first and then maybe you'll figure out that she's not a slut. Or, ask her about her past...you can usually tell by what people say about her, how she dresses, or her personality. Her ex boyfriends explain a lot about her too, and how they acted or treated her. And maybe, it can be the way that you treat the girl too. If you accidentally giver her a vibe or message then she is most likely to oversee it as something different and take the wrong message. Don't rush in a relationship if you don't want the whores and slutty girls.
