Professor's sex demo shocks bosses
A US university is at the centre of a storm after a sexuality professor known for his racy lessons allowed students to stay after a lecture to witness a couple using a sex toy.
Chicago's Northwestern University promised an investigation after news of the demonstration appeared in media reports and set off a blizzard of comments on social network sites.
"I am troubled and disappointed by what occurred," university president Morton Schapiro said. "I feel it represented extremely poor judgment on the part of our faculty member."
Mr Schapiro said that many members of the Northwestern community were disturbed by the incident and university officials said they had received many emails from upset parents and alumni.
"I simply do not believe this was appropriate, necessary or in keeping with Northwestern University's academic mission," he said.
The demonstration took place on February 21 after professor John Bailey's human sexuality class, which focused that day on kinky sex.
The professor, who teaches what some students say is one of the university's most popular classes, often ends sessions with an invitation for students to stay after regularly scheduled lectures to hear from sex therapists, swingers, transgender women and others.
According to students and one of the participants, Prof Bailey had invited a guest lecturer, Ken Melvoin-Berg, the co-owner of a group called Weird Chicago Tours, to discuss bondage and sexual fetishes.
Also there to answer questions were Jim Marcus and his fiancee Faith Kroll, who, according to student Justin Smith, was introduced as an exhibitionist "turned on by the thought of sex acts in the nude in front of large groups of people".
Students were warned repeatedly that they were about to witness explicit material and that they could leave.
