I like getting slaped in the face during sex. Is that weird?

My bf usually did it lightly and it doesnt hurt but one day I said fucking hit me and he slapped the fuck out of me. Then I said fucking hit me again so he smacked me in the face again but I enjoyed it. He was suprised that I liked getting slapped that hard. It wasnt hard enough to leave a bruise just a red hand print that faded in a few minutes.
