Yesterday happened to be the 10th birthday-slash-anniversary-slash-whatever you want to call it of Pornhub. And, to commemorate a decade of guys sitting in front of their computer and phone screens doing you know what, the site put together an extensive infographic to tell you pretty much everything you’d want to know about the go-to source of pleasure for friends, co-workers, and the like. (Here's the truth about how porn affects your sex life.)

One of the lists of data compilation on this massive infographic happened to be the top 10 all-time categories viewed by consumers of free pornography. The order, though enlightening, was not exactly unexpected. Keep a mental log of the ones you’ve helped contribute to over the years.

Coming in at No. 10 was “Hentai.” There’s probably a mountain of Internet think pieces that can be written about that. Feel free to keep them.

No. 9 involved men with larger-than-normal penises, because, after all, porn is about fantasy.

In keeping with the line of thinking that bigger is better, No. 8 was for porn devoted to well-endowed women.

Beating that out, at No. 7, was “anal." (If you'd like to make that desire a reality, though, then find out how you can make anal sex pleasurable for both you and her.)

At No. 6 was “ebony," and starting out the truly elite top five was “mature.” Following that at No. 4 was “teen (18+).”

At No. 3, we can find the porn world's embrace of the DIY attitude in form of the “amateur” category. Then, rounding out the list was the runner-up,“MILF.” And finally, in the very prestigious No. 1 spot, was “Lesbian.” (Take note: Here are three things lesbians can teach you about the female orgasm.)

Like we said, a lot of these weren’t too shocking.

Further delving into the statistics showed that the most popular category on the site every year from 2007 to 2010 was “amateur.” In 2011, the “teen” category took its one and only title. Then the world collectively decided they wanted women with a little more experience, as that was replaced by “MILF” for three straight years (2012 to 2014). In 2015, 2016, and (so far) 2017, the most preferred category has been “Lesbians.”

Which category will be next for 2018 and beyond? Doctor's visits? Face-sitting? Tow truck drivers blackmailing women into not giving them a ticket? The future is rife with exciting possibilities.

Anyway, though this is not exactly the classiest write-up, it’s vital information, nonetheless. Feel free to demonstrate this knowledge, along with your social tact, during lulls in the conversation at any number of events, including (but not limited to) family dinners, holidays, class reunions, and funerals.
