Is seduction a precursor to intercourse?
That entirely depends upon you.
It is not supposed to be fore-play.
Seduction is more refined; it delays, it teases, it plays. A conclusion is not inevitable or even required.
Should you desire coitus, treat it as you did seduction; make it another game.
This game can take whatever form your modern sensibilities desire: vanilla, kinky, femdom, self-gratification or old fashioned.
You decide. That is the important part.
