【Watch Hana ni Keda Mono: Second Season Online】

It’s been 10 years to the day since Pornhub launched. A lot has changed since then,Watch Hana ni Keda Mono: Second Season Online but one thing remains the same: we are obsessed with lesbian porn.

To celebrate their big anniversary, Pornhub took a look back at what their users have enjoyed over the past decade. And the results are… revealing. It turns out we’ve got a pretty voracious appetite, and we’re looking few very specific things.

So what exactly are all these people looking for? Well the most popular category of all time is “Lesbian.” That’s followed by “MILF,” “Amateur,” and “Teen.” As for the most popular stars? Lisa Ann is number one of all time with more than one billionvideo views. Riley Reid is in second place, with over 770 million views, and Madison Ivy earned third place with some 650 million views.

When it comes to what people upload the most, “Amateur” beats out the rest by a long shot -- no surprise there. That category has a whopping 2.2 million videos. The next closest genre is “Gay,” with 1.8 million videos. After that comes “Blowjob” with 1.3 million.

While we definitely don’t have the most wildly creative tastes imaginable, the scale of consumption at this point is pretty amazing, if you cast your mind back to May 25, 2007. While internet porn had existed for some time, you couldn’t type some combination of sex acts into Google and have an endless selection of videos at your fingertips for free. Now, well, it’s a totally different story.

Pornhub has been one of a number of sites that have completely reshaped the way we consume pornography. Within six months of launching, Pornhub had an average of one million visitors a day. By 2009, that number was up to ten million, and it was one of the top 100 most visited sites on the internet.

Today there are more than 75 million viewers each day. This massive level of porn-watching has definitely had a huge impact on the industry. Pornhub’s Vice President, Corey Price, told Mashable, "We’ve steadily democratized adult entertainment, improving the experience by tailoring our platform and offering a wide-range of content to adhere to our fans’ specific wants and desires.”

They’ve also had to keep up with massive changes in technology. When the site launched, 99 percent of their views came from desktops. Today 75 percent of their visitors are on mobile devices. They’ve even embraced new developments like VR headsets -- which would have sounded like pure fantasy to most people 10 years ago.

Pornhub is nothing if not interested in engaging their fans -- they’re known for stunts like offering VR porn for Mother's day, urging people to dress up like pandas and have sex...for science, and one very savage April Fool's prank.

So it's only fitting that to celebrate their big day they’re launching a contest to win one of 100 ten-year memberships to Pornhub Premium. To put yourself in the running, you just need to use the hashtag #PHtaughtme and find a social media-appropriate way to explain what exactly you’ve learned from watching their videos. That’s a lot harder than it sounds.

Should you win, you could use your subscription to watch every single one of the site's 10 million videos. It’ll take you a total of 173 years to do, so maybe don’t do it all in one sitting.
