The aim of this qualitative research was to gain insight into feelings of sexual shame and guilt, specifically to understand how young adults experience and differentiate these feelings, how the feelings develop and change, and which factors play a role in the development and maintenance of sexual shame and guilt. The study involved fifteen participants (eight female, seven male) aged 20 to 27 years, including eight non-heterosexual and seven heterosexual individuals. Data were collected through in-depth semi-structured interviews. The results indicate that participants distinguish between feelings of sexual shame and guilt, although they sometimes experience them simultaneously. Participants more often feel sexual shame through comparison with social norms, while guilt is more often felt due to a specific act or behavior. Both feelings have a negative impact on intimate relationships, with societal pressure regarding their sexuality being particularly felt by female and non-heteronormative participants. In the societal context, sexuality is discussed less than participants would like, and they particularly miss informed and open discussions in schools and healthcare institutions. Aging signifies predominantly positive changes for participants – acceptance of their sexuality and physical body, setting boundaries and better communication. These changes are highlighted by participants as crucial processes in reducing feelings of sexual shame and guilt, while for some participants, new causes for these feelings also emerge.
