ive had an older girl, she was actually a real women, 36 years old and WHAM*gggg*. it took me month but i got her. the trick is as follows: you have to start with normal talk for a couple of times, just some small talk first, then start to show interest for things she says, reads, works at and stuff. that leads to some more private-talk where you can bring in some(dunno how to say it in english right)funnies and maybe make some joke-like remarks maybe about kissing and stuff.that should lead to some flirting, and then just wait for the right moment and ask her for drinking a coffee with you one time, or invite her to a movie or something. if she agrees,gotcha!
