Any 12-Step meeting is usually conducted along similar lines, but most SA meetings are closed -- that is, only those who think they may have a sex addiction are admitted. In contrast, most Alcoholics Anonymous chapters have at least one open meeting a week, where people can go to find out what it's all about. It's understandable, though that the SA meetings are generally closed, since no one wants to share experiences, knowing others are there strictly out of prurient interests.
Not surprisingly, the Twelfth Tradition of complete anonymity is of paramount importance at an SA meeting. People will understand an alcoholic drinking away his or her paycheck, but are not so tolerant of the addict compulsively engaging in self-gratification on the bus. They could be driven from their homes if their addiction was known.
