Females wanting to have sex more than their male partner?

My husband and I have been together for a long time. Married just over a year. I always felt bad because I really never "wanted" to have sex. If he started getting a little frisky, then I typically always got in the mood but I never was the one to initiate it first. If we didn't have sex for weeks I probably would have been just fine. Since getting off BC I feel like my sex drive completely changed! I thought it was just because I was wanting to get pregnant but even if I'm not during my fertile time I just feel like I want sex so much more. Now my husband is the opposite. I feel let down because I have initiated sex and been turned down. I just always assumed men were always in the mood! So it hurt my feelings. It just seems weird to be flip flopped in that sense now. He still wants to have sex, it just seems like I want it more now! Anyone else in the same boat? It makes me feel like something's wrong with me but he reassures me it isn't anything like that, he just doesn't always feel in the mood.
