To the OP, its not so much about being nice, as being plain and boring. You can still be nice, but if you are too boring, then obviously no one will want to hang around with you. If you can introduce a little bit of "edge" and humour to your personality, that same lady will have a different perception of you. Its all subtle little changes you can make. I am not saying that you should become a dick to women, just introduce a little edge to your character. Teasing is one of the foundations of flirting, so you could poke fun at her or something she's wearing etc.
If you break it down, its probably your upbringing and social conditioning, that has encouraged you to be nice, polite and friendly around women, so it takes quite a while to introduce that edge into your personality.
I suggest you watch Californication, and pay close attention to Hank Moody. Just notice how he is always respectful towards women, yet he does poke fun at them and also dishes out some light insults. He is also sometimes a dick, but he always has the best intentions.
