(2) Bad date topic- how much weight your ex gained. You don't want your date to think you are a shallow jerk who will leave her when she gets pregnant, even if you are that shallow jerk.
(5) Bad topic- how much kinky sex you are into. Most women will go with the flow in the sex category, once they are into you, however you don't want to scare them off on the first date.
(6) Bad date topic- any weird cheapnesses you have. She doesn't need to hear that you don't keep the heat on in 10 degree weather or that you go to your mom's to watch Entourage so you don't have to pay for HBO; she will find this out soon enough, no need to burst her bubble right away.
