There have been several threads asking why women don't initiate sex more often, frequently causing their mates some frustration. Having lived a fairly long life, studied evolution in school, and studied female sexuality as a hobby most of my life, I'd like to offer one explanation. Most guys will agree that they are pretty much ready to go at the drop of a hat, but women are not - we are hard wired differently. What most women I've known need that most men don't, is foreplay. Without it, they have little interest in sex - it's kind of like a guy wanting to eat even though he's not hungry. Her appetite needs to be stimulated before she even starts to think about sex. So it's not surprising that, without foreplay, most women are not thinking about sex, let alone initiating it. I've also learned that, no matter how close we are or how long we've been together, it's not reasonable to expect our mates to be able to read our minds. One man's opinion, FWIW.
