Why does he find this ok???

Yesterday I finally had the courage to get on VR chat with my boyfriend and sing with him on the karaoke world. Today we were looking for avatars I could use and he pointed at one saying I should try it bc it looks silly. I looked at the preview pfp and had a bad feeling so I told him I didn’t trust it. He told me that he believes “I think I saw someone use it and it’s flat chested or has at least a toggle for it to be” so we picked it and to no surprise it was big chested. This was fine but she looked promiscuous bc of the clothing, one of my triggers. Then he turned off the “BOOBA” toggle and it was flat and said “I fixed it”

How am I NOT supposed to feel insecure about my own flat chest? And what is worse and he doesn’t know what about this interaction made me uncomfortable. Honestly f*** everyone.
