My friend is being weird??? Does anyone know how to tell him?

Im Grace, im 16. My friend lets say John (male, 16) is a good friend. Hes nice and all, a little weird. But recently he keeps replying to my posts and being really eager to see pictures of me and commenting things like “ very 😋😋 very 😋😋😋😋😋 you’re so 😋 so very 😋😋😋😋😋😋😋😋😋 i wanna 😋” under my posts which makes me uncomfortable but i dont know how to tell him??? It freaks me out.

It feels objectifying and awkward. Ive had a history of guys being really bothersome. It makes me want to cry. I can’t tell if im overreacting. I dont want to bring it up and cause a huge fight. Hes a good member of my current friend group. He says similar things on all my posts. I feel like i cant escape being objectified by everyone. I thought “yay john wont do this to me will he?” But no, i just want to be called “beautiful” or “pretty”, not “fine” or be told “i want to 😋” because were just friends. I just want a friend. He also gets mad when i dont wanna hug him, and for some reason really want a sleepover??? Ive always made it clear i dont want a boyfriend really. I just want a friend for once. :( i dont know how to say it.
