Take a shower and dress yourself smartly and bring a small box of chocolates or some flowers. When you were younger the girls cared less but now you are dating, show some respect for your partner.
If you take her out to a restaurant, don't pay with "buy one, get one free" coupons. Pay in cash, so that your girlfriend feels that she is really worth paying for. Keep the coupons for when you go out with your mother (who will appreciate your thriftiness) or your mate (who will not see or care how you settle the bill).
Finally, girls expect you to behave properly when you take them out, so, no raucous singing or belching and farting contests. Girls don't appreciate this behaviour, so just keep it for when you are out alone with the boys
Don't forget these five simple points and it will help you enjoy your dating and get you a further rendezvous with the same partner. Other people will advise you to be yourself when dating girls, which is good advice when being yourself does not mean going against the five points noted above. So here's to wishing you all the best with your future dating.
