AITA for posting a picture of my boyfriend close to me?

18F my boyfriend is 18M

Earlier he was laying curled up beside me with his head resting on me eyes closed, same time my dog curls up on the other side of me.

He’s looking really cute and I take a pic and put it on my Snapchat story saying need more hands can only pet one while on my phone, then another pic with a vote saying which one gets up first?

Later when he gets up he’s got a bunch of messages from his friends making fun of him for it, which they apparently continued to do later when they met up. Instead of telling them off, he asks me not to post stuff like that. Seems a little annoyed not really mad or anything but like he expected me to already know I shouldn’t have. BUT before he has given me blanket permission to post any pictures we take but he said this one was very obviously different. I get it’d a bit more intimate but we were both fully clothed.

Idk I don’t think I could’ve really been expected when he’s given me permission before but maybe circumstances do make it obvious and I’m just oblivious which ngl I generally am so like tell me if so.

Also I’ve never seen him annoyed about being made fun of before, him and his friends joke all the time idk why this is more sensitive to him. They were just making performative man references and calling him soft boy who likes to cuddle and is in touch with his feelings not like those other guys who are pigs, those kinda jokes and one of the weird ones kept saying he wants pegged. But that’s the extent of what I seen.
