Porn and pregnancy

I know that pregnancy is hard for the men, but I just feel like because I only want sex once a week doesn't make it ok for him to be masturbating to porn! I feel ugly enough as it is with acne and bloated belly I don't need to see that he's more worried about getting his kicks! I know he's a man and they have urged but I just don't feel like he thinks about how much stress and strain my body is going through! Everything I've sacrifed I used to love sex everyday! But I'm to uncomfortable already! How do you ladies stand on porn??
