I found this girl at the club, got her facebook and we've been writing. We went out once, but we're in different cities for now, so we can't do it often and we chat instead.

I tease a lot, she reciprocates and giggles. It's really fun, but there's doesn't seem to be that sexual tension. There are times I can turn things around and make the conversation more sexual. Then she responds pretty well and I'd say she's interested. Yet she rarely does it herself.

How do I make it more sexual through chat? Links are also well appreciated.
