If you talk to us, the worst thing we can do is indicate we aren't interested and you don't get laid. If you don't talk to us, you can guarantee you won't get laid.

Men who fully understand this seldom lack for female company, even if they're jerks. If that's too vague, think about the way a good trainer talks to a horse. Men who assume that every woman wants to be wooed like a prospect for marriage are almost as blind as men who who treat women solely as sex objects. Sometimes she'll be looking for romance, sometimes for a simple horny fuck, and often she'll be after something in between. The more accurately you zero in on her desire, the more likely you are to get yours.
