Sorry I'm late to the ball with an answer.
INTJs are good at stuff. We usually have a couple areas of expertise. If you can find out what they are, show interest in one of them and acknowledge his expertise. It frequently goes unnoticed, probably because it's untraditional or kept to oneself. But a lot has gone into building that expertise, and having it recognized is immensely gratifying. That will grab his attention, I assure you.
SecantSquared and Ace are right, though, that you musn't feign knowledge you don't have. Few things are more annoying than people pretending to know things they don't. But if you show interest, stay honest, ask a few questions and show appreciation for the responses, you'll definitely pique his attention.
I think your best shot (other than blowing him away physically) is to talk about what he's interested in. I know that's probably true for everyone, but I suspect a lot more so for INTJs. Acknowledging his strengths will set you apart from most people.
Are you still trying to make this man's heart orgasm? It's been almost a month since the thread started, you should let us know how it's going. I'd hate to think we're talking to an empty room now.
