Well, he’s not wrong. Ultimately it’s between him and the person he’s staring at if there’s a problem whee you stares (its not like there aren’t people who would be more uncomfortable with you staring at their face). Plus, I’ve always hated it in manga like this where the girl gets mad when the MC looks at her breasts, naked body, and/or underwear and she gets mad... and then she also gets mad when he doesn’t compliment her for it or ask/want to see them. I just don’t get people.
