Sex, pregnancy and, porn...

Is it wrong to watch porn 25 weeks pregnant? I use to watch it before I got pregnant to ya know "get off" but quit when I found out... The past couple months my SO barely wants to touch me he doesn't even hold me at night anymore. It's been almost a month since we had sex last and in find myself horny all the time.. But it just feels a bit weird thinking about watching porn.. Any other pregnant mommas have this issue or any advice? Might I add I feel huge and pregnant so it just makes me feel more unwanted that he won't even touch me..
