Hornier than my boyfriend

So my SO and I have decided to try to conceive. We have been together almost 6 years and live together. I feel like I'm always the one to engage in sex, and tonight sent me over the edge. He got home, I was in the shower and invited him in and he said no, so I shower and get out trying to be sexy and he's semi awake, I  tell him I'm horny and he says he's tired. I've literally been cleaning all day and he's been out having fun with his family. I go back in the bathroom crying because he turned me down (and he knows I'm upset) and comeback out dressed and he's sleeping. I am so frustrated and feel so unattractive. I hate being denied. Am I being overly emotional or have anyone else felt this way? Help :(
