My boyfriend is no longer sexually intimate with me and i don't know what to do?

[Yuy]

I have been dating my boyfriend 2 years 31st this month. I care about him and he cares about me, always holding me and cuddling with me. I see him often... I am starting to feel like something is wrong with me. I know he has no one else in the picture and he says he is stressed, but lately i have to practically beg for him to have sex with me. I tried spicing it up. I hold him and kiss him but he doesn't like french kisses any more, i kiss his neck, i mount him, i push him into the bed, wrap my legs abound him, smack his butt, he doesn't like me to grab him any more he asks me to stop and says "i am toot tired"... I talked to him about it he just says he is stressed out by work and a lawsuit. I show up at his house in just a trench coat and lacy laundry, "aw you look really good, do you want to but your Pjs on and watch a movie." my heart sunk. I even got in top shape and he still turns me down. 5'10 150lbs, I asked him if its me? he says no. I asked him if its some one else, he said no. whats wrong with me? It hurts to be turned down all the time, he said he likes to be the one in control so i stopped trying and its been 2 month since we have done any sexual things. he always asks for a massage, he turns me down for a 30 min massage. Its really hurting me inside to get turned down like that. I know sex isn't everything... I don't want to leave him, but i want my lover back.
