First thing I notice in a woman is her looks. In other words her face, her appearance, how she shows herself to the world.
Then I notice her lips and eyes. Does she have Angelina Jolie or chicken lips. Then I notice the way she carries herself. I like women that are strong but are not afraid to show emotion. She's not afraid to tell some guy to fuck off but at the same time when she see's what she likes she acts shy and hard to get.
She's definitely got to have a sense of humor especially in big crowds. She can't be one of those that gets upset at everything, I realize sometimes people say stupid shit and that's understandable to get upset but then move on. I love a woman that's into sports or other activities ie... going out and hanging with friends. I love women that are social but knows who her man is but doesn't mind being a little flirtatious.
Of course this comes after the initial boobs and pussy thought but since I can't use those....
