You are kidding yourself if you don't think some size is important to women. You don't have to be huge, but if you are like 6-7 with some thickness, and can actually fuck, then you are in pretty good shape. Look at guys like Lexington Steele and those guys in their vids. They don't fuck women nearly as well as some of the dudes with a normal sized dick. But a 4 incher will have a woman not wanting to talk to you anymore.
