Women are hard-wired to desire to be pursued. A tiny percentage of pre-qualified, modern and aggressive women might call, but by and large women are very averse to making the initial call. The game is: The man pursues the woman (in their minds), and she will usually consider making that first call to be far too aggressive for her to do. It will just "feel" wrong to her although she may not be able to articulate why. It feels that way because it goes against her programming and makes her feel too "forward".
