My boyfriend never posts pics of us?

We've been dating for almost 7 months and very much in love. But he hasn't posted a single pic of us. All his friends with girlfriends already have. Even one guy posted one after 3 months dating. I know i shouldn't care but it bothers me. Should i ask him to or is that too much? He did put my initials in his instagram bio when i asked though.
