In a cross-sectional study (N = 866), we explored whether internet pornography use with the partner was associated with sexual satisfaction, depending on partners’ relationship agreements about monogamy. Results showed that consensually-non-monogamous participants (CNM) used internet pornography more often than non-consensually non-monogamous (NCNM), or monogamous participants. However, CNM participants were as sexually satisfied as monogamous individuals, whereas NCNM participants were the least sexually satisfied and reported more sexual arousal difficulties. Also, CNM individuals included their primary partner in internet pornography use more frequently, and this was positively associated with sexual satisfaction with the primary partner.
