Many groups exercise complete control over interpersonal relationships. Leaders can and do tell people to avoid certain members or spend time with others. Some even tell members whom they can marry, and control the entire relationship, including their sex lives. Some groups require members to deny or suppress sexual feelings, which become a source of bottled-up frustration that can be channeled into other outlets such as harder work. Other groups require sexuality, and a member who hangs back is made to feel selfish. Either way, the group is exercising emotional control.
