One interesting find was the following
which had the following information

MasochismCredit: Ioannis Pantzi, Shutterstock Pain is pleasure for masochists, who get aroused by beatings, bondage and humiliation.
Among consensual masochists, however, major maladjustment appears rare. A 1987 study published in the Journal of Sex Research of men recruited through sadism/masochism support groups and a sadism/masochism magazine found that only 6 percent were emotionally disturbed by their own sexual behavior.
Pain isn't always a pain. Sometimes it can actually feel good.
People experience pleasure during a painful stimulus if the stimulus turns out to be less bad than they were expecting, new research suggests.
"It is not hard to understand that pain can be interpreted as less severe when an individual is aware that it could have been much more painful," said study co-author Siri Leknes, a psychologist at the University of Oslo in Norway, in a statement. "Less expected, however, is the discovery that pain may be experienced as pleasant if something worse has been avoided."
Personally, I would rather be spanked than having an argument, upset feelings, coldness, or simply being unhappy for a few days.
