Motivation for the hubs??

We are starting our journey to having our first baby and I'm curious how you motivate your husband to BD? We never have sex on weekdays because he's so exhausted after work and I'm mentally drained. So we do it on the weekend. I understand that we'll need to BD much more often during my ovulation days. How do I motivate the hubby to make this baby happen? I don't want it to feel forced. And he's as ready for a baby if not more ready than me!
