SAN FRANCISCO (CBS SF) — Kink.com, a San Francisco-based pornography production house, is offering a new kind of sex-education class – with live demonstrations by porn stars.

The classes, being offered in San Francisco’s Armory building, feature live demonstrations following a lecture, according to an article on SFist.com.

Porn star Rain DeGrey told SFist, “They have to sit through a lecture before we get to the good stuff. We do techniques, physical response and have a question and answer period before moving on to the demonstrations.”

The weekly classes have been going on for a few months.
