absolutely no sex drive

Amber
So, I'm only 20 years old & I've been with my current bf for about 2 years & I have absolutely no sex drive at all whatsoever. I was on the pill, and told my doctor about the problem & she told me most birth controls will have that effect. So I went completely off the pill & use only condoms I've been off the pill for almost 4 months now and hasn't seen any change at all. Is something wrong with me? When we do have sex it's always great & I finish every time but it's getting started and the desire for it that I'm lacking. This problem is really taking a toll on my relationship I've tried everything. Help
