provocative pictures

hey ladies, my boyfriend just suggested starting an instagram account to post provocative pictures. personally, i am not super comfortable with it because of my body but i also feel like he doesn’t care who sees what and that’s not really helping my self esteem. how would you feel if your significant other wanted to do this? would you do it/consider it? why or why not? would you feel a bit upset if he didn’t seem to care about other men seeing stuff like that?
