My(27F) bf(33M) pulled my hair and got angry at me because of a comment I made about hair pulling

My bf and I have been together for a few months.
I know too much about my bf's past sex life. it is my fault because I was noisy and asked way too many questions.
Immaturely, I retorted "wellll my ex used to pull my hair harder than you do"
it was a dum and immature comment, and I feel very bad for saying it. Its not even true..as my ex never pulled my hair and my current partner is my first real sexual partner.
Anyways as soon as I said it, he pulled my hair very hard and flipped out on me. Went to the other room sitting on the floor freaking out crying that I mentally abused him and now he has that image in his head.
Obviously, it was not during intimacy, so the way he pulled my hair hurt a lot.
I do not think my comment was an invitation for him to do it but I am wondering if my comment could have been misconstrued as such?
tl;dr: My bf pulled my hair hard and it hurts. Not sure how to proceed after this argument.
