Pornhub Sexual Wellness Centre director and sex therapist Dr Laurie Betito said the data revealed women were now more empowered in all areas of life.
"2017 seems to have been the year where women have come forward to express their desires more openly," she said.
"From the #metoo movement to prominent females the likes of Hillary Clinton and Nikki Haley on the world stage, women are feeling more empowered and they have found their voice. This is a sign of things to come."
She also explained the enduring popularity of the Lesbian category.
"Lesbians have been the number one fantasy of men since the beginning of time. For the men that aren't likely to ever have a threesome with lesbians, this is an ideal way for them to live out their fantasy," she said.
"We can't ignore women viewers though. For women that have a soft fantasy or curiosity, lesbian porn allows them to explore that part of their sexuality without risk. Of course, for bi or lesbian women, this category is an obvious choice."
Dr Betito said virtual reality porn allowed viewers to "indulge their fantasies in a risk-free and non-threatening manner".
Most viewers — 67 per cent, in fact — used their smartphones to watch porn in 2017, while just 11 per cent used Internet Explorer.
