There's a lot of data to be had in porn. Word usage, positions, speeds, etc. Since data is the new porn these days, data about porn is like, DOUBLE porn.

Luckily, there are researchers out there who've realized this. Sexualitics is a site dedicated to publishing research on data mined from porn sites with APIs available. Currently they have a database of 800,000 xhamster video metadata pieces, and are doing n-gram analysis of descriptions.

For instance, this chart shows the usage of "milf" versus "teen" over the past 5 years.

You can track their research via the @sexualitics twitter account. They've also got a pre-print of their first publiciation available for reading, and all of the data is available on github.
