Im not cheating... Am I?

Look my SO and I have been together for 5 going on 6 years. We aren't married or have any children together but we are ttc. I do have a daughter who stays with her dad every other week. So when shes gone my SO and I have the place to ourselves. You would think yeah time to get freaky!!!! Nope. Not even touching and kissing. We pretty much do our own things at home. I go to the room and watch TV he watch's TV in the living room. I try so hard to get him to give me some. Its sooo frustrating, he is the only man I want. When its been months I start masterbating and thinking of him when he makes orgasm(omg its so good). But then I start thinking of my last partner and watching a lot of porn. I even fantasize about being with woman just to get me off. Its sad really. Is that cheating? He is the only man for me. I hate that I have to make an appointment just to make love. I feel so lonely lately, we are suppose to be this great team everyone talks about. What do I do? Buy a toy and hope he gives me love. Do I leave or stay?
