Those are valid reasons IMO

I find that once I start to O again I get mine back, which means any hormonal contraception for me really reduces my sex drive.
Also, the tired factor plays a big part, but I am happy to stay up late if DH helps me with housework. If I don't feel run off my feet, just tired, then I am up for it. Don't know if this is relevant to your situation, but DH is less disappointed now he knows what he needs to do (e.g. THE DISHES!) to get me in the mood.
