Why does my friend talk about my boobs all the time?

I have a friend and I'm kinda into him. Sometimes i flirt very subtley. I talk to him about all sorts of issues in the world. We also share jokes but he mostly wants to discuss my boobs. When he starts talking about my boobs a lot I start joking about his dick cause I can't bear to stay quiet or intimidated. There are some specific words for boobs in our language that i find derogatory but he keeps on using them and he knows that i don't like those words. I feel that he sexualises me all the time by such words. I think it is slightly disrespectful too. Is it a red flag?
