My boyfriend playfully hits me. Should I be worried?

My boyfriend playfull punches my arm out of nowhere. It’s not hard but it hurts. I told him one of my fears is a man raising his voice. He playful raises his voice and laughed when I got scared. I looked somewhere he told me not to look and as soon as I looked he yanked my head a little too hard.
