Is this normal at this point of your relationship?

Well when sex not what you want it to be in a relation ship I do it too. I would watch porn with him get more sexual go to the adult toy store have him fulfill some fantasies. Communicate that you have more sexual desires so he knows, and if he loves you he will do them. Good? The key is communicating you needs and thoughts with you sig other. And if you don't you sill always be unhappy. Good>?

Talk to a professional counselor or therapist. Is there something in his behavior that is turning you off? You have a young kid, you are probably busy and he probably isn't paying as much romantic attention as before. If someone can help you determine why you aren't interested, you can talk to your fiance and try and to see if you can fix your relationship. If you can't, at least you can get out knowing that you tried to fix the problem.

Break up with him. It's pointless to stay in the relationship when you dream of cheating on him.
