From Fight the New Drug (it’s an anti-porn site but I’ll use their statistics and leave out the moralizing):

"While pornography consumption for young adults has been repeatedly reported to be approximately 75% for men and 30% for women, these rates are considerably lower than those found in this study. In this study, consumption rates of men were generally consistent (91–99%) across time frames, though women’s consumption varied more widely (60–92%). Interestingly, this range in reported rates for women is consistent with the variability found in previous literature, which may be indicative of a profound impact of assessment methods (Hald et al., 2014).

Notably, 11% of women in our sample primarily consumed written pornography compared to other pornography modalities (with written pornography being 90–100% of the total pornography they consumed […] Alternatively stated, if written pornography had not been included in this study, our consumption rate for women using pornography in the past month would drop to approximately 49% from 60% reporting consumption. A similar pattern of decreased endorsement would have occurred across all time frames.

So video and photographic pornography is targeted more towards men as the primary consumers.
