He just doesn't get it

Jay and I talked yesterday...about sex. I was telling him that I would like him to be more aggressive especially when it's been a while since I've had sex. He said he understood, told me to put the kids to bed early, and meet him at the door when he came home. So, I did all that...still no sex. I am convinced that he is just unmotivated. He's just not a 'take it' kinda person. Before he left for work, I had told him that I think he's afraid to do what I ask. Last night, he said that he had been thinking about it at work and he just didn't understood how someone forcing me can be such a turn-on. Like I said, he's just not that kind of person.
