Porngram: a Google Trends for niche sexual interests powered by 'sexualitics' An interdisciplinary team of researchers has created a Google Trends-like tool called Porngram that maps the evolution of keywords in the titles of 800,000 porn videos. It allows users to enter in any number of keywords to see how often they appeared in the titles of porn videos uploaded to porn site Xhamster between 2007 and February 2013. It allows you to see that movies tagged with "footjob" have been on the rise at the same time as those tagged "handjob" have been falling. You can compare your own keywords here. The Porngram tool was built off the back of the Sexualitics dataset, scraped from Xhamster and Xvideos to become the subject of a research paper into porn data analysis.
The Xvideos dataset (which looked at 1,200,000 videos) lacked the upload date, meaning that it wasn't useful for offering up trend data over time. Having done this, the researchers started to draw semantic connections between keywords. Pourquoi n’existe t’il pas de véritable préservatif pour les lesbiennes? - Sexy SouciS. OkTrends. Good Sexual Intercourse Lasts Minutes, Not Hours, Therapists Say -- ScienceDaily. Satisfactory sexual intercourse for couples lasts from 3 to 13 minutes, contrary to popular fantasy about the need for hours of sexual activity, according to a survey of U.S. and Canadian sex therapists.
Penn State Erie researchers Eric Corty and Jenay Guardiani conducted a survey of 50 full members of the Society for Sex Therapy and Research, which include psychologists, physicians, social workers, marriage/family therapists and nurses who have collectively seen thousands of patients over several decades. Thirty-four, or 68 percent, of the group responded and rated a range of time amounts for sexual intercourse, from penetration of the vagina by the penis until ejaculation, that they considered adequate, desirable, too short and too long. The average therapists' responses defined the ranges of intercourse activity times: "adequate," from 3-7 minutes; "desirable," from 7-13 minutes; "too short" from 1-2 minutes; and "too long" from 10-30 minutes.
