My peer reviewed, academic sources say you are wrong. By a lot dear....
Frankly, if you want to get down to more current psycho-analytic theory, consensual BDSM is the Superego's sublimation of our more animalistic needs that our Id screams at us to do. The Id is our reptile brain - eat, ********, sleep (Eat ALL the things!) Ego is our more realistic brain incorporating reality (one cannot eat ALL the things - my stomach will burst) and Superego is our social and moral structures (I cannot eat ALL the things because my stomach will burst and its stealing)
Jung (Freud's fanboy and a fav of mine) would suggest most BDSM is Shadow Play, or working with our Ego's rejected self qualities. Nasty things like sexism, racism, murder, torture, and greed live in our Shadow. The Shadow is the monster who chases you down in your dreams at night - as Jung postulates everything in your dream is a reflection of Self. Confronting your Shadow is a key part of Jung's dream theory and unifying the Self.
As someone who is kinky, and has a foundation in psych PLEASE FOR THE LOVE OF ALL THINGS PURPLE AND FUZZY STOP USING OUTDATED INFO! Nothing is worse than spreading outdated - dis proven knowledge. It hurts people. It insults people. And worse, it makes it harder for me to live my life as a kinky human being because people "think" I will murder them in their sleep because I like to be tied up and beaten.
As I am currently aware the DSM - 5 does not deviate from the DSM-IV-TR's stance on sexual masochism and sexual sadism. Both of these listings assert that it only becomes a disorder when it impacts someones daily life negatively and/or causes distress to the person and/or when it involves non-consensual acts. Then and only then is it a mental disorder.
Kinks ARE NOT mental disorders, ARE NOT "repressed feelings from past trauma and abuse". They are natural human variance in sexual taste. While I still have access to peer review journals, here are few. All are peer reviewed and retrieved from psychinfo's database. If you would like population data, sampling size, and sampling methods I will be happy to fish that out for you - only if you ask. All of these journal articles are saved on my laptop.
"Conclusion. Our findings support the idea that BDSM is simply a sexual interest or subculture attractive to a minority, and for most participants not a pathological symptom of past abuse or difficulty with “normal” sex."

"Although psychoanalytic literature suggests that high levels of certain types of psychopathology should be prevalent among BDSM practitioners, this sample failed to produce widespread, high levels of psychopathology on psychometric measures of depression, anxiety, obsessive-compulsion, psychological sadism, psychological masochism, or PTSD. In fact, on measures of clinical psychopathology and severe personality pathology, this sample appeared to be comparable to both published test norms and to DSMIV-TR estimates for the general population."

"Therapists believed that an accepting, nonjudgmental attitude toward BDSM was the most crucial element of cultural competence. Every therapist we interviewed discussed this issue. Some described situations in which clients had been alienated or traumatized by the unaccepting or judgmental attitudes of previous therapists:"

“Regarding the major personality dimensions, our findings suggest that BDSM participants as a group are, compared with non-BDSM participants, less neurotic, more extraverted, more open to new experiences, more conscientious, yet less agreeable. BDSM participants also were less rejection sensitive, whereas female BDSM participants had more confidence in their relationships, had a lower need for approval, and were less anxiously attached compared with non-BDSM participants. Finally, the subjective well-being of BDSM participants was higher than that of the control group. Together, these findings suggest that BDSM practitioners are characterized by greater psychological and interpersonal strength and autonomy, rather than by psychological maladaptive characteristics.”
