This sounds very much like D/S to me. These feelings are occurring in the context of sex and as such are sexual feelings. Please don’t ask me why they occur because the explanation has been debated by no less an authority than Jung and Freud. This type of sexual feeling seems to predate even written history, and once writing did occur it has been the subject of texts and passages in every following century. Sexual behavior is generally considered acceptable if it does not do any real harm to the individuals involved. Monitor your feelings, perhaps in counseling, to see if you are harming yourself in anyway. Do your feelings have anything to do with your parents spanking you? Potentially, that could be the case. Will that create problems for you? Maybe yes, maybe no. I can’t tell you what to do. If you were in counseling you could develop the personal relationship which would allow you to be very open and discuss your sexual feelings with complete freedom. I would recommend counseling. Good luck.
