Want a baby but hate having sex

I don't know what to do ladies. Ever since I had my last baby who will he 2 In January I've hated sex. I don't want to be sexual with my husband at all and this has taken a toll on our marriage, friendship and everyday life. He doesn't feel wanted and I don't know what to do to make me want him. My problem now is we really want another baby but to do that you gotta have sex lol so I'm in a dilemma. Now I will say this... Even tho I hate sex we still have it 4-5 times a week ???? what are some things I can do to get my sex life back?
