Pregnancy body

So I'm 8 months pregnant and this morning was a rare one, I woke up in a great mood after sleeping a full night , and not long after I woke up my partner did too and I tried to subtly initiate sex, but then he got up and went for a shower and unfortunately for him he forgot that his Bluetooth was still connected to the speaker in our bedroom and I discovered pretty quickly that he had gone for a shower to watch porn and have a wank, he literally picked porn that was set in a shower I guess to make it more realistic😕 Now I'm not one to take issue with him watching porn when I'm away and stuff but I was right there in the bed and he chose porn over me, am I right to be a little upset? He tried to deny what he was doing at first when I went and confronted him and then tried to say he didn't want to have sex with me as he was worried about hurting the baby but I don't believe that because he would have asked me if it was unsafe ,, so yeah I feel pretty disgusting about my body at the moment, I know that he's grossed out by my belly & all the other things that have changed and knowing that he needs something else to get him going sucks 😣
