Guy I am dating won't let me post on social media. Who is in the wrong?

I have been dating this guy for 5 months. I recently posted a tiktok video of myself where I smiled in a flirty way in the video. He got extremely pissed at me and told me to delete it because he claims I am seeking validation and attention from other men and believes that I should only seek attention and validation from him. Am I in the wrong?
