Looking to learn more about sadomasochism? SM Gays is a not-for-profit social and educational group for gay men interested in consensual, sexual sadomasochism. Meeting since July 1981, its aim is to encourage safe and lawful SM practices through sharing of information among people with similar interests. The group is unfunded and run by volunteers. Every month the group holds a Discovery Night in Central London where you can learn more about SM techniques and meet other people with similar interests. There is no membership requirement or dress code and the atmosphere is friendly and informal. At present these events attract around 100 gay men.
