Should I be worried, because my boyfriend doesn’t post pics of me on Instagram?

So my bf & I have been going strong for a while now. I’ve known him for about 11 years, but we really began dating about a year ago. Since this past year we’ve gotten so close. I met his family, close friends & he’s met my friends and family. We took a trip to Vegas together also. We are with and talk to each other a lot!!

This past weekend one of his friends got married, we went to the wedding took beautiful pictures together for the first time. I told him to post it on Instagram. He didn’t say no, but he didn’t do it. He seemed very hesitant about it. Idk why this is annoying me so much. He doesn’t post a lot on Instagram though, in fact his last post was in the beginning of May. When he does post it’s usually only memes or a photo of him.

We planning a trip for Punta Cana for his 30th bday with all of his friends, and I want him to post pictures of us there. I don’t want this to be a problem in our relationship. So, my question is should I be worried about this?
