Would you get a little offended?

So I just started dating this guy and it’s a LDR.

We watch movies over the phone or video call most nights.

Well whenever there’s a girl in the scene and she has a nice figure or whatever, he always makes a point to comment on it saying stuff like “oh I love her titties” or something along those lines.

Now obviously you can tell by now I’m an insecure person. I don’t get super offended but it does get annoying cuz he does it a lot and whenever I even talk about one of my guy friends, he gets jealous...... sooo idk. And this relationship is pretty new and I feel for me to be having issues, even though it’s small, isn’t a good sign? This is my first relationship btw and I’m 18, he’s 21.

Ik I should talk to him ab it but I don’t feel comfortable bringing it up. Like I don’t want to seem controlling or to bother him. Idk. Maybe I’m not even ready for a relationship 😩 I really really like him though.

Someone help please.
