That's the kind of reaction you WANT from a girl.
Anytime a girl says any of the following things (this isn't an all inclusive list btw), you can pretty much bank on the fact that you are doing something right:
You suck!
You are into yourself.
You're such a d1ck.
a$$hole
Jerk.
You're not my type.
A short list, but my mind is shot right now.
Of course, it always matters how you react to these things, and it also matters the tone with which it is said (of course). But you should be able to figure out how each of those things are said based on which one she said, and know if the tone is right or not.
Putting your body pic up is actually a pretty good move. Don't load up an album with it or it will come across wrong.
But one or two shirtless pics showing off your body? Girls eat that sh1t up.
