Pornhub knows exactly what you're watching, and how long you're watching it for. That's a fact. Deal with it. And since the streaming site gets more than 20 million unique visitors a day checking out everything from BBW to bukkake to leprechaun porn for St. Patrick's Day (yes, that's a thing), they've amassed a giant trove of data on the world's masturbatory habits. 

That's why we know that more women than ever before are watching porn these days, or that Alaska loooves step mom porn, while most of the nation is looking for lesbians, but BBWs are also skyrocketing in popularity. It's how we know that when the snow came down last winter, northeastern cities beat on, and why we have proof that "Thanksgiving blow job" is a really popular search on the fourth Thursday in November. 

Now, thanks to some prodding from Vice, Pornhub has revealed exactly what type of porn gets people off the fastest. The company looked at its data to see which categories of videos were watched for the shortest amount of time when compared to the average viewer, who spent nine minutes and 20 seconds on the site.

Overall, the videos that apparently got people off the quickest were these categories, with "Red Head" taking the top spot for quickest finish, getting people off a full 163 seconds faster than that average. 

  • Red Head (163 seconds faster than average)
  • Hentai (152 seconds faster)
  • Blonde (150 seconds faster)
  • College (141 seconds faster)
  • Small Tits (134 seconds faster)

The category of videos that people watched the longest were "young/old" videos, which are videos featuring older men having sex with much younger women.  Those videos were watched for a full 113 seconds longer than average. Indiana University professor Paul Bryant told Vice that's likely because it's older guys, who normally take a little longer, who are into those vids. 

Things looked a lot different when the data was broken down by gender, though. Women watched Hentai (Japanese-style animated porn) for 195 seconds longer than average, possibly because they're more into the stories, Bryant told Vice. When it came to what got women off the fastest though, he had no explanation at all. Here are the women's top five: 

  • Handjob (169 seconds faster)
  • ​Solo Male (116 seconds faster)
  • College (105 seconds faster)
  • Asian (68 seconds faster)
  • Gangbang (50 seconds faster)

Which leaves us with a serious question: Would a woman come instantly if she watched the perfect storm of Asian men in college jerking it alone?
