Only my personal experience, of course. The few woman who have agreed to meet to fuck have all shown up. The many, many guys I have attempted to come over for a blowjob or mutual head resulted in more than half of them flaking out. It takes much longer to find a woman who wants to get together for sex, but once they have decided to cross that line, they are much more apt to show up than men. That’s the way it has been for me anyway.
