Unwanted in This so-called life

Today has been a good day up to this point. I hinted to my husband that I wanted to have sex tonight when we both got off work. He informed me that he would be too tired later. I feel so rejected. Have you ever felt so unwanted and sexually frustrated that you masturbated with your spouse sleeping right next to you? I can’t even count the number of times that I have. He tells me that I never want to have sex with him which is completely untrue. I just get tired of always having to initiate it. We have had many discussions about this but it doesn’t seem to be resonating. So I will continue to lie awake listening to the sounds of my lover snoozing wishing he would touch me. Sorry if this is too graphic for some.
