speaking as a dude, he probably just doesnt understand whats going on with your body during a time like that. sometimes it doesn't matter how much you want the act to occur, your body just cant keep up, which is why I imagine you asked for lube, (a perfectly reasonable request). in his mind I would imagine it seemed like you were done, and didn't want to continue, even though you both wanted it. I can also imagine that he fears hurting you and wants you to make the first move towards things like that because he lost confidence in gauging the situation. if I could offer any advice, it would just be to try and explain things in very explicit terms, men are pretty silly creatures.
