Fiancé watching a lot of porn...

I know he’s a man and usually I don’t care about this type of thing, but since I got pregnant I care a lot. It makes me feel like I’m fat and gross and like I could never measure up to what he’s watching... simply because I’m pregnant. Has anyone else felt like this? Please tell me I’m not alone. I’ve been super self conscious since I got prego and I hope it’s kind of normal.
