That implies that you DO sleep with some guys. And if you do, at 12 then I'd classify you as a slut.

You obviously have no one controlling you. No one giving you the limits, examples and direction that a 12 yr old needs.

By asking this question I think it bothers you that people think your a slut. So what does that tell you? It really doesn't matter that much whether you are one or not. Its how people perceive you. And if you don't like people perceiving you are a slut, then stop being one. Cover up more, cut back on the makeup, stop playing up to boys. Act more your age.
