I think a man that at least tries is showing that there will be a potential second date. And if a guy doesn't try to seal the deal, then he is not interested. And I know of no men on earth that wouldn't at least give it a shot unless they were not interested.
I'm a female and I want the man to at least make the move. I want to control the move. I want to be able to rebuff the move.
If the guy doesn't call after that, then he's an a$$.
As for me? The two men I had very long term relationships with didn't have to wait too long. I figured if it didn't turn out well in THAT area, someone should just lose my number.....
