psychology professor allowed a couple have se+

 Northwestern University's president said on Thursday that he is "troubled and disappointed" that a psychology professor allowed a couple to engage in a sex act involving a motorized sex toy in front of dozens of students, and is calling for an investigation.

Hours after accounts of the February 21 class appeared in local newspapers, including the university's defense of Professor John Michael Bailey's decision to allow students to witness the act, Northwestern President Morton Schapiro strongly criticised the lecturer.

"I feel it represented extremely poor judgment on the part of our faculty member," Schapiro said a statement issued by the Evanston university.

A guest lecturer had been discussing bondage and sexual fetishes during Bailey's human sexuality class. According to published reports, a couple at the lecture decided that a video the students were watching on the female orgasm was not realistic and gave a live presentation involving the sex toy. Schapiro said it did not matter that the incident occurred after the class was over, that attendance was voluntarily and that the students were warned of the explicit nature of what they were about to see.

"I have recently learned of the after-class activity associated with Prof Michael Bailey's Human Sexuality class, and I am troubled and disappointed by what occurred," he said.

"I simply do not believe this was appropriate, necessary or in keeping with Northwestern University's academic mission," he said.

Evanston police say it will be up to the school to determine if the demonstration violated any local ordinances. The guest lecturer asked the students if they were "ready for a live sex show," student Justin Smith told the Chicago Tribune.

At that point, Faith Kroll took off her clothes and she and Jim Marcus climbed on the stage and, as about 100 students looked on, the pair demonstrated the use of a motorized device with a phallic object attached to it. The lecturer, Ken Melvoin-Berg, told the newspaper that the students were told about issues such as safety and consent.
