Do you know the percentage of women that would rather drink a glass of wine than have sex with their spouse? 30%! 
We need to get to work guys. Wine is great and all, but it shouldn't be a subsitute for sex! Let's face it:
All us guys want is for women to want to have sex on a regular basis without having to cry, beg, manipulate or coerce. Is that asking too much? Well, of course not, assuming that you start taking into account the physiological and hormonal differences of the mystery woman that you share your life with. In other words, it's time to use science to your mutually beneficial advantage. I always say, "Work smarter, not harder"...
