How do you go from being the 'girl next door' to the object of his desire?

Take note from the movie "The Girl Next Door." minus the sex star aspect, this sounds like what you mean. Have a sexy way about yourself and make things happen, but at the same time be inviting and friendly. Once you show him your interested do little things to keep him thinking.

This is a good question. I have a friend who is into sports like baseball and football and on game day she is one of the guys. Sweats/ jersey/ flip-flops whatever. But on Saturday night when she gets dressed up, SHE is not messing around and is no longer one of the guys. It's a phenomenon in itself, I know. But she has two distinct attitudes and she knows how to use them wisely. I've observed a difference in when she wants to mess around and when she wants to get serious. Use what works to your advantage, sometimes it's all in how you flirt and not what you wear, or sometimes it's a combination.

You're very pretty, so this should be easy - It's all about the attitude, let the guys know that you know that they want you - you're not necessarily going to attract quality guys with that attitude, but it will make you the sex object you are looking for.
