I think that's typical, if what I think I say is as witty as I think it is when I say it.
Well, that may not be typical.
You know what worked for me as an ISTp? You have to take it slow. If you attack, he will flee. If you just make your interest known VERY clearly, he will take the next step. But you have to be crystal clear that you are interested, but not too much.
So you don' say, "WOW I want you." (run away!)
You should demonstrate that he would have a zero percent chance of failure if he asks."
That sound weak? From my perspective, the women drive the courtship. We are ALWAYS interested if she looks good and would be receptive. If she's TOO interested, she must be desperate. (run away!)
So if you think you've gone too far, back off, keep the channels open, but the ball is his now.
