Why do taken guys need porn?

why does guys need porno when they got a gurl friend? i dont think it should be like that? i absolutly HATE it, bc like alot of other gurls, i think it is decrasful for women because the gurls that dont or cant look like that, you know how bad that makes us feel? bc apartenly thats how a “perfect” gurl should look like or be. They should have big titties, with a skinny tinny waist, good legs, and looks. but really if they get more excited looking at them, then whats the point of staying with them. i dont think my bf is opsessed but he should really consider my opionin, cause he knows i got self esteem issues with myself, and when he calls them hot them that hurts, cause i knoe i could never look like them.. it hurts and he knows it hurts me, but i mean i dont think i would mind so much if he didnt tell me he had some or that he thought they were hot. if he just got them, with out me knowing i think that would be ok. but i asked him what was soo interesting about little sluts that show off there f**kin bodies to other men that they dont even know?? he told me that it was interesting bc they got boobs, well dont there gurl friends have em to? or do they just like fake ones? if so then whats the point. id really like to know.
