Boyfriend has warned me about his temper is that a good thing? Should I be worried?

My boyfriend who I've only been with about 8 months is very honest and open with me, we are with each other but he’s warned me about a few things and one is his temper sometimes.
He’s never been angry at all with me yet but he’s worried that one day when he shows it that I won’t like it and I’ll get upset.
I’m similar, we both have tempers maybe but is this a good or bad thing that he’s telling/warning me? Should I be worried?
