Thanks for clearing it up, but I still don't get this kind of stuff/fetish. (Sorry I don't know how to call it)
Giving up the own personalty/look to please someone and to hurt someone at the same time is not my cup of tea.
Maybe I'm not perverted enough
Stuff, fetish, kink, or call it what you will, I speculate, that it's all about the brains response to our involuntary hormonal chemistry caused by, stress, anxiety, anger, fear, and love, among others combined with our natural sex drive (also hormones) and the resulting feelings. I think it's not only the sexual act, it's all about emotional control or the real lack of it. The sense of being victorious or defeated, surrender and domination, etc. Couples often engage in fighting with each other over nonsense, and after, the makeup sex turns into a highly charged sexual event, without ever realizing what they are doing. All of these emotional roller coaster rides, conclude with a hormonal release as a much stronger-than-normal orgasm or quite the opposite, ending with a case of blue balls... after that, your kidneys filter out the excess chemicals in your bloodstream and then you go pee
