Sex?!?

I'm 35 weeks pregnant but the last few times me and my boyfriend have had sex (it seems to be a planned event now so I can be "prepared", as I have too much of a struggle having such a huge tum...shaving etc) he has to go out and buy alcohol for himself when he knows we are going to have sex. It's making me feel very unloved. On a daily basis he expects a blowjob from me...it all seems to be on his terms even the planned nights....and I'm getting fed up of it now! I feel disgusting.
