Where did it go?

Sophie
Hey Ladies,
So recently my boyfriend and I have noticed my sex drive is way down and I don't know why? What could be the cause? We used to be at it like rabbits but now it's hardly ever. I still find him as attractive as heck and I love him to pieces, nothing has changed - except my libido. 
I've been on the pill for 2 years and he and I have been together just over one so I don't think it's that?
