Boyfriend says he cant ever joke with me..

Last night my boyfriend and i got into another argument due to the lack of affection and how we communicate.. And during this argument, he mentions how he cant ever joke with me because i take things the wrong way... But i actually dont. I can play and joke, but if there's just some things that shouldn't be said... Like for example, i asked him last night to give me an example of what it is that he feels that he should be able to joke with me about, and he says " like if we out in public and we see this girl and i say she's got a nice body but that thang probably stank, you should respond back with a " yeah you're probably right" but i think that's a little much.. Why would you say anything about another female around me anyway?? I know men look, but i personally dont find it acceptable for him to say things like that... My response def would be "Like why you looking at her body to begin with?? " am i wrong for feeling that way?
