Insecurity from BF

I don’t know why but I can’t help but feel insecure from the girls my boyfriend views on his fyp on tik tok or Instagram. I’m not mad at him for admiring another women, I allow him to do that. I do it too. I would say I am attractive, have a nice hour glass figure, and a pretty face and hair. But my goodness, these women he views are big boobs, big butt, curves, beautiful faces, perfect figures. I can’t help but feel insecure because I don’t look like these women. How do I feel better about myself?
