Husband has zero sex drive

Not sure I want to stay married when we hardly have sex. My husband doesn't have a strong sex drive. I miss feeling desired by a man. When we do have sex I don't enjoy it. It is boring. He wants children but we don't have enough sex to get pregnant. Then I discuss lets adopt but its always me bringing it up and researching that. I feel like time is just passing by with no changes. It has been like this for the past three years. I don't see how things are going to change.
