Seduction and Ttc.

Having trouble getting my husband to ttc during my fertile window. For years I had a very needy libido before we were ttc. Now as I am older and tired of rejection sometimes I just don't ask for it because I don't want to hear his excuse. So know we are ttc and he believes that we should not worry about when it will happen. But he doesn't ever want to during the right week. Once a month not anywhere near my ovulation is getting us nowhere. I've told him my concerns but he takes it as me pressuring him. Any I deas of how I can seduce him? I'm about ready to slip him some viagra so he has to.
