Sex and pregnancy

I've always had a high sex drive that my bf has never been able to satisfy. He just isn't really into sex and prefers porn and jerking off a couple times a week and will have sex with me like maybe once a week if I nag or ask. I never just initiate it anymore because I get turned down so much. But now that I'm pregnant I can't even feel confident enough to have sex with him. His favorite porn is teenagers and now that I'm not thin and tiny like that I just feel disgusting. He says it doesn't bother him at all but trying to get sex from him doesn't work much anymore and so I've Givin it all up. It's been 2 months since we've had sex (and it was only about once or twice a month before that) and I pretty much live on my vibrator and porn. I even feel guilty for that because of the poor baby being vibrated to death! Lol. I just can't wait to get my body back and my flat stomach! Maybe then we can sex again. I just sort of wish he wasn't so used to porn being amazing and interesting and better then me. We've been together for over 8 yrs and he has no imagination or real sex desire, why would you need one if porn provided everything you could desire to see. So we have a boring sex life and of course porn is going to win. But since it's totally normal for a guy to love watching porn I'll just have to wait it out. Maybe after the baby is born and waiting so long to have sex he'll be interested a little more.
