is pointing out other good looking people ok??

my boyfriend thinks that there is nothing wrong with pointing out other hot girls to me. He will just say something like that girl is hot or sexy or he will point out a specific body part like her legs,boobs or arse. he says that it is all innocent and that he is just admiring another good looking person and he seams to think that he has said the same things to past girlfriends and they don't have a problem with it.i think it is just a mean thing to do! Am i being stupid and making something out of nothing?
