Porn watcher

My boyfriend is obsessed with porn & looks at it all the time but not with me or around him....and always is looking at other girls that walk past everywhere I see his eyes follow their asses. I just had a baby so it makes me feel so self conscious cuz I'm a little bigger to begin with but I just don't know. All I can think of is how much I must repulse him and it's sad and destroying my self confidence. He says he loves my body because it's where his children come from but still like it's interfering with my happiness. I don't see why he insists on watching when I am willing to have sex with him pretty much whenever. Ugh sorry rant over....
