Introduction: Problematic pornography use and frequency of pornography use showed positive, but small-to-moderate associations in previous studies indicating that these two aspects of pornography use are related but yet may be considered as distinct domains of pornography use with potentially different antecedents and consequences. In the case of other behavioral addictions and problematic online behaviors, different motivational patterns emerged behind problematic use and frequency of engaging in a given activity. However, this assumption was not tested with respect to pornography use. 
Objectives: The aim of the present study was to examine the similarities and dissimilarities in the motivational background of problematic pornography use and frequency of pornography use. 
Methods: Structural equation modeling (SEM) was employed to examine the associations of pornography use motivations, problematic pornography use and pornography use frequency (N=1,082; females=537, 49.6%).
Results: According to the results of SEM (CFI=.942, TLI=.935, RMSEA=.064), problematic pornography use was positively and weakly related to sexual pleasure (β=.09, p<.05), fantasy (β=.12, p<.01), boredom avoidance (β=.14, p<.01) and emotional avoidance motivations (β=.20, p<.01), whereas it was positively and moderately related to stress reduction motivation (β=.43, p<.01). Frequency of pornography use was positively and weakly related to stress reduction (β=.14, p<.05) and boredom avoidance motivations (β=.23, p<.01), and positively and moderately related to sexual pleasure motivation (β=.34, p<.01).
Conclusions: Our results suggest that it might be important to take into account the 
 motivational background of problematic pornography use and the frequency of pornography use to reveal more fine-grained differences between intense and problematic users.
