FIGURE 5.

(A) Depicts predicted relationship satisfaction (vertical axis) as a function of actors’ (x-axis) and partners’ (y-axis) frequencies of solitary pornography use and their interaction for cases that reported mean levels of shared pornography use in Study 4. (B,C) Do the same for the prediction of sexual satisfaction and sexual dissatisfaction, respectively. In (A), the lack of significant interaction resulted in a flatter prediction surface where partners with dissimilar frequencies of solitary pornography use were not notably lower in relationship satisfaction than partners with more similar frequencies. In (B), sexual satisfaction scores tended to be lowest in cases in which couple members were most dissimilar in their frequencies of solitary pornography use (left- and right-most corners of the plots). According to regions of significance tests, participants’ own solitary pornography use was negatively related to their relationship satisfaction if their partners’ used pornography alone less than 1.80 times a week but was otherwise unrelated. Conversely, in (C), sexual dissatisfaction scores tended to be highest in cases in which couple members were most dissimilar in their frequencies of solitary pornography use (left- and right-most corners of the plots). According to regions of significance tests, participants’ solitary pornography use was positively related sexual dissatisfaction if their partner indicated that they used pornography less than 2.17 times a week, otherwise their pornography use was unrelated to their sexual dissatisfaction.
