This is hilarious! Someone wrote software that manages a "parallel" dating style.
In addition to storing each woman's contact information and picture, the Girlfriend profiles include a Score Card where you track her sexual preferences, her menstrual cycles and how she styles her pubic hair.
It's called Girlfriend X, but that's a link to an article about it. I didn't go to the actual website. I just thing it's amusing someone went through the trouble to do this. Maybe there's a demand for it. \shrug**
