By not sexual towards me

So I'm 25 weeks pregnant and my bf isn't sexual towards me because I only like to do doggy or me on top because missionary hurts. And he's blaming me for not being sexual towards me... Like I've confronted him and asked and he says well you can only do you on top or doggy and that doesn't get me off. I feel like shit. I feel ugly and ashamed and I don't even like looking in the mirror anymore. I just wanna be appriciated
