Your Girl Is Most Likely Lying!
I know I know. You've heard it before. "Is it in yet?". 
This link will tell you all the things your girlfriend won't tell you, and it even tells you things she will tell you. Want to get her real opinion? Want to see how you measure up? Well then, heh heh, come on in and see where you stand when it comes to the dicky dicky dong dong. Girls, read it and laugh, or read it then hide it before your boyfriend sees it. And remember: have fun!
