Advice! Am I exaggerating!? NEED ANSWERS

Okay so since being pregnant I’ve became even more self conscious about my body. Now it wasn’t helping me seeing my SO watching videos of girls with big butts or boobs. I’ve asked multiple times for him to stop & explained how it makes me feel even worse about myself. Now last week, he watched videos of girls “working out” but the camera was just angled onto their asses. We argued bad & he told me he was sorry & wouldn’t do it again cus he knows how much it bothers me. This morning I wake up around 5am to see him watching another one of those videos! Expect this one is just of a girl shaking her ass around her house. Like always I approached him on it, this time a little more hostile because I’m tired of feeling this way & repeating myself to him. Then he has the audacity to tell me he wasn’t watching it when I JUST SEEN HIM CLEARLY WATCHING IT! (I’ll attach a pic below of how the girl had looked). But long story short, we haven’t talked most of today now, he’s been out with his brother all day & he just doesn’t comprehend where I’m coming from or why I feel this way. Tbh I wanna do something to get him back but I don’t wanna be so childish. Am I over-reacting or have every right to feel this way after it happening multiple times now?
