摘要:Purpose: The co-occurrence of substance abuse and excessive sexual activities is acknowledged in research and treatment practice. Men seem particularly at risk for developing excessive sexual activities. Excessive sexual activities complicate substance abuse treatment, and clients with such co-occurring difficulties have considerable treatment needs. It is therefore considered important to investigate how male clients who had enacted excessive sexual activities, perceive their excessive sexual activities, and themselves. Design: Interviews were performed with five male clients in substance abuse treatment, who had enacted excessive sexual activities. The interviews concerned the participants’ perception of themselves and how they came to enact excessive sexual activities. The interviews were analyzed using thematic analysis. Results: Two major themes were identified. One theme concerned overwhelming shame and difficulties to discuss sexuality in treatment. The second theme concerned how perceptions about masculinity had influenced sexual activities. Sexuality was described as an absent topic in their previous and ongoing treatment, and the participants described a need to discuss sexuality. Implications: It seems important that future studies investigate how excessive sexual activities might be identified and handled in treatment. It also seems important to investigate how gender-perceptions might influence excessive sexual activities. As a suggestion, practitioners should address sexuality, shame and perceptions about gender during treatment.
