I've never taken birth control before and I am supposed to start Lutera next week. About 2 weeks ago I took plan B for the first time and since then have had almost no sex drive when I am usually a sex fiend. Will starting birth control completely kill my sex drive? Or does it just lessen it for a while then come back to normal? I'm afraid of starting then not even wanting sex anymore, seems like that would defeat the purpose of having birth control.
