When on a date with a girl, keep these four simple rules in mind:
Do your best to look good on your date. Do not just show up at your girl's door to pick her up for a date in your old jeans and t-shirt. Put your best effort into looking and smelling good. Take a nice long bath, shave, put on some nice clothes and some cologne (just do not go overboard with the cologne). You could even bring some flowers or chocolates if you really want to make an impression.
Do not make your date feel that she is not worth the full price. Keep your discount cards for when you are out with your friends or family. There are situations that call for thriftiness but trust me, a date with someone you are attracted to is not one of them.
Never, never, never talk about your ex girlfriends. It is a complete no-no. Even when girls ask about it, they do not want to hear about all the previous girls in your life. Girls just ask about it to be polite.
Farting and burping contests should only be for boys' nights out. Even when they are drunk, girls will not be entertained by this. It is plain gross to them.
