I would say, contact him. You've done so much work with yourself. Let's see now if you can have that extra little thing called B on the side...
I would go direct. A phonecall if it is possible. An then I would send the underwear (of course I liked the idea, you knew I would, right?). And then maybe oIll send you THE sex calendar, and Lisa the corset and Michelle a gun (!!) and we get him off guard and he becomes your slave...
Appart from the jokes, he probably thinks you are over him. He probably thinks that if you felt anything you want have contacted him by now. Let him know you love him. Don't tell him, don't get me misunderstood, put that special warmth to whatever you decide to do and let him feel it...
