RecruitingBehavioural interventionPiloting the Competence in Romance and Understanding Sexual Health CurriculumThe goal of this clinical trial is to learn whether the CRUSH curriculum is possible (feasible), whether it fits the needs of the adults it is designed for (acceptable), and shows initial signs of being helpful (efficacious). CRUSH is a group-based behavioral intervention plus 1-1 coaching designed to provide sexual education and improve the skills of autistic adults for intimate relationships. The main goals of the project are to: * Evaluate the feasibility and acceptability of the CRUSH curriculum in the context of a clinical trial with a waitlist control condition. * Initial exploration of how the CRUSH curriculum works and whether it is helpful. Participants will complete: * A screening call. * Confirmation of clinical characteristics (autism features, language ability, cognitive ability). * 3 visits to assess knowledge and behaviors related to dating and sexual health at each point throughout the training curriculum (before beginning, midway, and after finishing). * 20 sessions of the CRUSH curriculum plus 1-1 coaching sessions. After each session, provide feedback about the session.
