Sex Drive Non Existent

I'm 29 years old and I have a very very low sex Drive. It's been like this for over 5 years. This is a problem. I thought it might have been my birth control, but I've been off of that for 3 weeks now and nothing has changed. I just got married in March to my husband. I'm very attracted to him. I just don't know what my issue is. I feel like I have to pretend to want to have sex with him. What do i do? What can I do?
