Is it normal im enjoying my masochistic personality?

As a masochist i have my limits of being liking pain. like how i hate slapping in the face or choking. stupid crap like that. i never really told my bf about my masochistic personality because i knew for a fact he wasnt into that type of thing. well he is a little but not as much. Hes just afraid of hurting me badly. but im a tough girl and i know my limits. like how i love it when a guys rough with me. and how i enjoy hard spankings. and him saying how bad and dirty i am for liking such things. But i try not to bring up my masochistic personality to much around him because i know hes not thatt depp into that type of thing even though i am. so is it normal that im enjoying my masochist side this much?
