"In our multinational, cross-sectional survey of pornography use and sexual response in women, higher frequency of pornography use predicted greater sexual functioning across all outcome variables during masturbation, yet had no deleterious effects on sexual outcomes during partnered activity. Across masturbation and partnered sex, lower levels of educational attainment and the presence of ongoing anxiety or depression were the two most consistent predictors of orgasmic dysfunction in the regression models. Greater sexual relationship satisfaction, in contrast, was associated with more favorable outcomes during partnered sex. Taken together, these findings suggest that the frequency of pornography use per se does not contribute to sexual problems during partnered sex., However, it could well be that a subset of women use erotic materials to compensate for psychosocial factors (e.g., dissatisfaction in one’s sexual relationships, ongoing anxiety or depression) that independently impinge upon sexual responsivity."
