Harvard University hosted an anal sex workshop teaching students how to 'put things in your butt'.

The talk hosted by adult shop Good Vibrations on Tuesday was one of many workshops held for Sex Week at the Ivy League university, which counts Malia Obama as one of its students.

Around 50 students attended, according to college paper The College Fix, to learn how to stimulate nerves in the rectum, how to use anal beads, and how to avoid infections.

The host, Natasha, also discussed 'the stupidity of abstinence', the value of 'practice, practice, practice', and a primer on using medical-grade butt plugs.

It is the second time the university has held a talk on anal sex; the first was in 2014.

'There are two types of people in this world, people who watch anal porn and dirty f***ing liars,' Natasha said, according to the Fix.

Anal sex, which stimulates the multiple nerve-ending in the anus, has been practiced for centuries, Natasha explained. It is particularly stimulating for men, since the prostate is next to the rectum.

She went on: 'Not all men have penises, not all women have vaginas,' adding that 'the butthole is the great sexual equalizer. All humans have a butthole.'

According to the Fix, Natasha also detailed some relaxation techniques, and warned that porn is not the most reliable and safe resource to learn about anal sex.

She handed out sex toys for students to hold and look at while explaining how to use them.

At the end of the talk there was a raffle for some of the shop's more 'high-end' sex toys, and there was a box of free toys and pamphlets, funded by Planned Parenthood, for students to take home.

Despite President Obama's repeal of a ban on consensual sodomy, 12 states still have anti-anal sex laws on the books. Those include Oklahoma, Mississippi, Florida, North Carolina, South Carolina and Utah.

Nonetheless, pegging - where a partner who doesn't have a penis uses a strap-on dildo to penetrate a partner who does have a penis - became a hot trend in sex last year, popularized in part by an episode on the hit show Broad City.
