This is a manual of group activities, field-tested in Zambia, that are intended to help organizations and community groups promote sexual well-being, strengthen communities and prevent HIV. The activities are grouped in five topics that are meant to be presented in sequence:  gender, sexuality and vulnerablity; sex and relationships; sexual violence; working together; and making a plan. All the activities include facilitator’s instructions and require resources that are available in most communities. The manual also includes guidelines for involving stakeholders, forming a team and preparing for activities, plus facilitation tips and descriptions of key skills for group facilitation.
