No birthday present

Hey ladies, 
I feel so petty asking this, but I want your opinions. 
It was my birthday yesterday, my first birthday with my current boyfriend and he didn't buy me a present. We went to the zoo and then he organised a picnic afterwards. 
Should I be upset that he didn't buy me a gift? His birthday was in September and I took him ski diving, a seafood lunch and bought him a watch. 
Am I being materialistic?
