Sexual masochism
Sexual masochism is engaging in repetitive, sexually arousing intense fantasies or sexual urges for over a period of atleast 6 months. Individuals with sexual masochism are sexually aroused on the act of being humiliated, beaten, choked, bound or otherwise made to suffer during sexual activity.
Those who experience these desires of sexual masochism suffer with significant distress or impairment in social, occupational and other important areas of functioning. For those who do not suffer, are described to be having masochistic sexual interest. The masochist experiences sexual pleasure from physically or psychologically receiving pain, suffering, and/or humiliation.
Individuals with sexual masochism act on fantasies in private; usually these would include self-mutilation, sticking themselves with pins, or giving themselves electric shocks. If a partner is involved, the acts may include blindfolding, restraint, spanking, whipping, cuffing, and other forms of humiliation.
