FIGURE 4.

(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 3. (B) Does the same for the prediction of sexual satisfaction. In both figures, 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’ almost never used pornography alone or never used pornography (partners’ solitary pornography use <–1.15) but was positively related to their relationship satisfaction when their partners’ used pornography alone more than once or twice a week (partners’ solitary pornography use >0.38). Similarly, further regions of significance tests found that sexual satisfaction was negatively related to participants’ solitary pornography when their partners used pornography alone less than one to three times a month (partners’ solitary pornography use <0.85) but was positively related when their partners used pornography alone more once a day (partners’ solitary pornography use >1.95).
