My boyfriend constantly calls other girls hot

My boyfriend of 9 months is always checking out other girls. for example today, he saw a girl. she was very pretty in my opinion, but he went ahead to tell me that she was extremely hot, was a “goddess” a “queen”, had an amazing butt, etc. he has also made comments to me the he would ‘bang’ other girls. I in no way expect him to only think that i am the only attractive girl in the world but it really hurts me when he talks & stares at other girls like this. I will admit that i am insecure & am trying to learn how to accept my self. today as he was going on about this girl, i turned to him saying, you’re literally so annoying. he took a lot of offense to this. i have no idea what to do in this situation, what is your opinion?
