No sex after we moved in with each other?!?!?

Ok so when we started dating we stayed with each other nearly every night give or take like twice a month but we did not official live together and now that we are six months into our lease im lucky if he tries anything on me once a week and im to nervous to say anything to him about it. Before we officially lived together we had sex three times a week minimum sometimes twice a day id even get woken up by him trying something. And when we do have sex now its not passionate at all no foreplay or anything he just gets the job done and thats that :/ makes me feel like he has gotten too use to me.
