Husband watches Porn but doesn't touch me

So we have been married for 5 months now, and I am also pregnant at the moment. Due to the quarantine husband has been laid off and been at home since this all started. We have never had sex ever since we found out we're pregnant and that has been 4 months now. His reason is, he is out of shape. No hugs, kisses, and sex. No physical touch of any sort. We're basically just room mates now. And then I caught him twice already that he keeps on watching porn.

I asked him if he finds me unattractive now that I'm pregnant, and would rather look at other women's body in the porn site and he said it's not the case. But I honestly don't know what to think anymore. Lack of physical touch is depressing already, and knowing he watches this videos made me more insecure than I already am with all these changes of pregnancy is doing to my whole being.

Is it normal?
