While the minimum commitment is 6 months, the average time is about 10–12 months; some group members choose to stay for a 2–3 years or more; others move to the monthly group.

Given the nature of the concerns of group members, we require this commitment. It would otherwise be disruptive to the group to have new members "just try it out" for a few weeks. This group represents a significant commitment and members need to know that others in the group will be invested for a sufficient amount of time in order to feel safe and express vulnerable feelings and thoughts. Group members also need sufficient time to practice making and keeping agreements, as well as to experience attachment-related conflicts and repair of relationships in the group.

There are typically between 5 and 7 members at any given time in the group. 8 is the maximum number (we have tried 9 members at different times, but it can feel too big).

While it is not a requirement, we strongly recommend that group members have individual therapy at least once per month. This can be done with one of the OCSB group leaders, or a therapist of their choosing.

This fluctuates—on average about once every 3 months there is a new opening. Sometimes sooner, sometimes the wait can be 6 months or more.

In the OCSB therapy group, members create their own sexual health plan, including their own boundaries—the only requirement is that their boundaries are consistent with the 6 principles of sexual health. Group members also encouraged to talk to each other during group, sharing their feelings, reactions, support, and feedback with each other, facilitated by the group therapists.
