Should in ask my bf to?

So I am very private. I am not active on social media. However, i know that a lot of people think “posting” their relationship not to brag but just to tell people you have someone, is a way to agaim let the world know that ur in a relationship. Idk it seems very trivial to ask of him, and a bit immature but i do feel like it’d ease my anxiety a lot knowing that our relationship is somewhat publicized because right now i feel like a hidden secret.

I was on facebook and i saw this guy i went on a couple dates with posting his girlfriend and idk. It just made me feel like i never really had anyone who was willing to show me off or anything. It’s a little depressing because i do feel like every human in this world deserves that and deserves to feel like their partner is proud to be dating them!
