Husband thinks I'm FAT 😭

So.. ever since I got pregnant my husband barely ever initiates sex. The other night I had to basically beg him to take a shower with me and he didn't even get stiff, literally no reaction. He gets in bed and doesn't even try when it was clear I wanted it. I finally woke him up and seduced him πŸ˜‚ Has this happened to anyone else? How did you handle it? I feel like he just thinks I'm fat and unattractive now. It definitely doesn't have anything to do with him being Afraid of "hurting the baby" or anything like that. And yes, I have talked to him. Of course he says he doesn't think that! Don't know any other reason for his decrease in sex drive though 😩
