Why does my husband keep comparing me physically to his ex-girlfriends?

We have been married almost eight months and ever since we've been together he has always CONSISTENTLY compared me to his exes and sometimes even pornstars? He's compares things like my boobs, private area, weight, thighs and booty with other women. I told him on about seven occasions that I don't like it because I feel like he's trying to bring me down and humiliate me. And he keeps doing it! Everytime he talks about anything on my body somehow his exe's breasts or bodies ALWAYS come up it's like inevitable. Everything he compares me to is PURELY physical never on a mental level. He's said a lot of things that I think I will never forget. Here are some examples. " I want to get you pregnant so you can pick up some weight." "Oh your getting thick I love it I must be doing something right." "You are the smallest woman I've ever seen." "But your perfect I love you just the way you are and I'm not trying to compare you." "Your breasts are so small and petite compared to my exes and other women I've seen but I like yours better." "You are the smallest women I've been with my exes had a slim waist big breasts, hips and thighs." Which doesn't make sense to me because I wear a 36D which I think is pretty average and I'm 5ft4 and 146 pounds I just have a very toned body due to me doing sports growing up. "My exes breasts were the size of watermelons shaped like circles and yours are perkier shaped like a pear and the size of cantaloupes." "There breasts would sit up more than yours and go to their chin in a bra but hang down real low and would stuff my face in them it was too much." "Your breasts are not really small I prefer to call them small because I consider anything below a 40DD small." " I couldn't grab their breasts with my hands like I could grab yours." He says he's attracted me and that he loves my body so much better so why is he ALWAYS comparing and showing me he's interested but not that interested. I've never had this issue with any other guy ever.
