How to Impress a Woman, Tip # 7

Know a woman’s clitoris. Now I am assuming here you boys know where to find it
at least — if you don’t, get your hands on an anatomy book, and fast!

The key is not too much pressure, but to little either. Actually, a good way to perfect your technique is to practice is with your computer’s mouse!

Grab your mouse and turn it upside down. Then run your finger along the ball, applying just enough pressure to make it move. Move it in a clock-wise motion, then in an anti-clockwise motion. Then up and down, and across. Keep practicing this, varying your technique. This should help you get it right! And you will never be able to look at your mouse the same way again.
