My Husband seems does not like announced our relationship

I have been married for 7 months, so far he such a great husband for me. But one thing that I cannot understand till now, he does not like if I post something about our relationship (like couple picts, or just sweet and romantic status) on social media. Last week I tag him on my post in fb together with my other family, but the he hide it from his timeline. I ask him why?? And he said he just does not like if his personal life being consumed with other people, it is normal if I feel a bit upset with him? Or I am just too agresive about this issue? Please your advise laddies.
