ADVICE NEEDED: Who do I report my husband's excess demand for sex to?

My husband's sexual libido is so high that as his wife, I am exhausted and tired. He demands for sex from me like every other day and my refusal has caused issues between us. It is not like I am trying to run away from my marital duties but sometimes I just need him to understand that the rigors of work and taking care of our three little children takes its toll on me and sex is sometimes the last thing on my mind. I might just want to rest and as hardened a he is, even when he sees that I climb the bed by 11.30pm and I am to wake up by 5.30am to start preparing the children for school, he doesn't care and still demands sex from me. I am Tired. Now I am thinking if I should talk to my Pastor or his Father so that they can talk to him for me. Is this a right or wrong move?
