In Europe, an organization called ReviseF65 has worked to remove sadomasochism from the ICD. In 1995, Denmark became the first European Union country to have completely removed sadomasochism from its national classification of diseases. This was followed by Sweden in 2009, Norway in 2010 and Finland 2011. Recent surveys on the spread of BDSM fantasies and practices show strong variations in the range of their results. Nonetheless, researchers assume that 5 to 25 percent of the population practices sexual behavior related to pain or dominance and submission. The population with related fantasies is believed to be even larger.
