OTTAWA - Curators hosting a raunchy sex exhibit for schools are getting a spanking from the heritage minister.

The Museum of Science and Technology is hosting Sex: A Tell All Exhibition, which includes a climax room with a round leather bed, a screen showing aroused genitals, a man's voice describing his orgasm, naked statues with light-up erogenous zones, and video commentary from adults singing the praises of multiple partners and "friends with benefits."

It was designed for children 12 and older and school field trips, complete with follow-up quiz games for teachers. The admission age has increased to 16, but younger students can still see it on field trips.

"The purpose of the National Museum of Science and Technology is to foster scientific and technological literacy throughout Canada," said James Maunder, spokesman for federal Heritage Minister James Moore.

"It is clear this exhibit does not fit within that mandate. This content cannot be defended, and is insulting to taxpayers," Maunder said. "We have expressed our strong concerns to the president of the Museum, and we encourage Canadians who are concerned to do the same."

The display includes signs with printed questions and push button audio answers to questions like, "Sometimes when I look at a handsome singer, my panties become wet. Is this normal?"

An animated video showing naked young people how to masturbate was originally included but was removed after parents previewing the display were horrified.

The exhibit was crafted by the Montreal Science Centre with input from sexologists, and organizers hoped it would "fill in gaps" left by changes to the province's sex ed programs in schools.

It cost $800,000 to build. The Museum of Science and Technology gets about $30 million from federal taxpayers per year.

"If you want to hold something like this that's fine, it can be done with private money not tax dollars," Canadian Taxpayers Federation Derek Fildebrant said. "The Sex Museum in New York is totally private, no tax dollars are spent, it doesn't even have charity status."

The exhibit opens to the public Thursday.
