He doesn't want me

My SO and I have been dating for 6 months. I'm the beginning we had sex every day 2 to 3 times. We move in together and it just stopped. I have tried to tease him and go down on him. Do little dances but he doesn't do anything. There's no for play and it's just a quick hump and dump. Idk if I'm doing something wrong. Any advice. Please.
