PornHub has revealed "lesbian" was the most popular search term entered by British visitors in 2015 while Kim Kardashian was one of the most searched-for individuals. The XXX-rated website has published eye-watering annual statistics showing it received 21.2 billion visits last year with the UK the second most porn-hungry nation behind the United States.

India, Canada and Germany make up the top-five, and the average time spent on the website shot up by four seconds to 9mins 20secs. The average time spent on the website by a UK user was 9mins 18secs – seventh overall and more than three minutes shorter than the Phillippines, at 12mins 45secs. Cubans, on the other hand, lasted just 5mins 11secs.

Just over a fifth (22%) of PornHub's UK viewers were women and the age group most likely to watch pornography were the 18-24s, which accounted for 32%. The over-65s made up just 5%. The most common actresses Brits looked for were Lisa Ann, Lebanese-born Mia Khalifa and reality TV queen Kim Kardashian.

The figures also show that Brits prefer the more discreet platform of a mobile phone to watch their porn than any other device. More than half (53%) used their smartphone to access PornHub compared to 29% who used their desktop and 18% their tablet.

Almost 88bn videos were watched overall last year – or, 12 videos per person on the planet – which translates to more than 4.3bn hours of pornography. "In 2015 alone, we streamed 75GB of data a second, which translates to enough porn to fill the storage in around 175 million 16GB iPhones," the website reported.

Visits tend to be between 10pm-12midnight and in terms of year-on-year growth, the term "giantess" – a larger-than-life woman getting intimate with very tiny men – led the way with an impressive 1091% gain.

For all the debauched search terms, 'love' remains the most commonly featured word in PornHub comments.
