sex..

So I'm currently 36 weeks pregnant. My SO and I recently moved in together! I'm currently a week away from graduation and he is a week away from going back to school. We are beyond happy together, besides the fact of pitty fights now and then. Nothing major just both getting anxious in all with the first baby coming soon. However I have an odd sex drive, sometimes it's random and I just really crave it. But I feel like I can't get him as into it as we use to be and with this growing belly it's become quite a chore to even have sex. I ask him at times to have sex and he often says no or not tonight. Which I respect, and leave it alone. However I am a sexual person, and I want it! Any opinions on how to spice it up or ways to have crazy sex while being in your third trimester??
