Advice please!

I've been with my husband for over two years and we have a beautiful baby boy. Ever since The first time I've had sex with him my sex drive has been through the roof and at first we had a lot of sex. After we started living together, the sex has declined and my sex drive is still extremely high and want it daily. I would settle for having sex at LEAST once a week and I'd be happy. We only have sex like once every two weeks. How do I tell him that I want more sex??? I've already tried hinting at it and telling him. Idk if he thinks I'm joking or what. Sometimes I just think something is wrong with me.
