Pornhub claims that there are countless insane search terms on their website, but the latest popularity data of certain fetishes have taken us by surprise.

If we open up an incognito window and log on to your favourite (ethical, we hope) porn site, you'd expect to see videos of threesomes, BDSM, girl-on-girl etc but what you may not expect to see is a footjob.

According to the site, foot fetish porn is hugely popular, with 'footjob' being the 140th most popular search term on Pornhub. It's no small…feat, they say.

Some other popular foot-themed searches feature foot worship, foot fetish, lesbian feet, milk feet, foot slave, tickling feet, giantess feet, foot domination and feet licking. Jesus H. Christ.

Pornhub mentions that those searching for foot fetish porn were likely to search for femdom, ballbusting, facesitting, cuckold, bondage and gangbang porn in the same viewing session.

It comes as no surprise to anyone that young men are 55 percent more likely to watch footjob porn than women. Visitors aged 18 to 24 are the biggest fans, and then 25 to 34-year-olds.

Interestingly, footjob popularity decreases with age. Visitors over 65-years-old were the least likely to watch the genre. High heels and stockings are the most popular foot job porn.

However, a 2018 Pornhub report noted that sneaker porn was becoming more watched by the year. Men were also 55 percent more likely to search for sneaker porn.

Pornhub Gay page users were 1124 percent more likely to search for sneaker porn, which is most popular with 35 to 44-year-olds.

Some consistent search terms were; sneaker worship, sneaker sex and sneaker fetish, as well as known trainer brands (Converse is the most searched). 

Nike was most popular with those on Pornhub's gay pages.

Foot fetishes generally seem pretty common, with a 2007 study from online fetish discussion groups finding that “feet and objects associated with feet were the most common target of preferences.”

In fact, almost half (47 percent) of fetishists in the study were into feet. Famous faces like Tyga, Ricky Martin, and Quentin Tarantino are known to be open about their penchant for feet,

"A lot of people wonder if they are weird or perverted for having a foot fetish, but I can tell you it's actually quite common," Goddess Aviva, a lifestyle and professional dominatrix, told Refinery29. "It's also a lot of fun."
