Why do I crave sex more then my spouse??

I don't know what it is but since I can remember I've always been the one in the mood, trying to get him in the mood, touching him, etc. I always want to do it and he never does, could something be wrong with me or is this normal? I feel like we have switched roles. I always hear stories of women who don't want to put out, but in my case it's him.. Please, I need some answers 😕
