Masochism involves humiliation, or being made to suffer.
Sexual masochism is not considered to be a psychological disorder unless it causes unhappiness or problems in work, social, or family life. Some masochists require pain or humiliation in order to function sexually. Other masochists may engage in more typical sexual activities at some times and masochistic activities at other times. Some people may act on their urges by hurting themselves or tying themselves up. Masochists often seek partners to tie them up, humiliate, blindfold, or hurt them.
