Hellppppp

My man has been watching porn and videos on youtube of girls with fat asses and big boobs and me myself have a big butt for a white girl and almost a double d in a bra. Everytime i see it, it makes me feel like im not good enough and everytime i comfront him about it he just say that im perfect but why would he watch those videos when he has me? We have sex and play around all the time too but he still watches the video any suggestions to help or make things easier.
