Is it normal?

Is it normal to not want to have sex with your partner but still be super in love with them? My sex drive is almost non existent at this point. Is it because I got on birth control or that we started living together? I literally cannot bring myself to be in the mood. Whenever we have sex, I just want to finish. What’s wrong with me? I love him a lot and want to satisfy him in the department but anything sexual I don’t want to do. I would rather just cuddle up.
