I think that men don't like to perform "on demand". Maybe if you didn't put the little stars on the calendar, and just kept track on your own, and then seduced him at the right time. I also think it's probably sorta important for your DH that you are interested in having sex with him when it's NOT your fertile time. Otherwise it makes him feel like you're only interested in having sex for the sake of TTC, and not because you're attracted to him. That probably makes him feel kinda unwanted.
