It's nice to be wooed, but guys like to feel like a woman is reciprocating. It is like positive feedback in a way. "Oh, she called me! I must be doing something right." I'm not saying you should always do this. I think it takes a lot more effort for guys to become emotionally attached to a woman (yes, a generalization based on my experience with men), and allowing them to pursue gives them a healthy dose of the chase they seem to enjoy. The less serious guys fall by the wayside and you can make a better decision.
However, the need to be wooed also lies in the desire for attention. Some guys are just shy and may need some positive feedback from you to continue to pursue. If he feels like he's not affecting you enough to reciprocate a little, he may just ditch the whole effort.
And honestly, avoid texting at first. They're great for short little messages and updates, but texts are emotionless and become tiresome. They are easily misconstrued because everyone interprets them differently. If I call someone and they don't answer, I leave a voicemail specifically asking them to call me back. I feel a better connection when I can hear someone's voice.
