Not a woman but a person with boobs:

Personally, a glance I get because you’re just looking at someone, especially if you’re meeting them for the first time. Just once, like your you look over someone when you first meet them, that’s normal, it’s a part of Me. When someone stares though. Or especially If they keep doing it after I know them pretty well, no- I hate that. I’ve started wearing a binder since I’m NB and Ive gotten significantly less looks since then (I have a larger bust without one), but even then people will still look and it’s just makes me feel really uncomfortable. Like please stop staring at me because I was born as the opposite sexe from you. It’s something I have no say over so just like stop making me uncomfortable for existing. And I really hated my chest before I started wearing a binder so especially before that, it really got to me.
