A sex education exhibit that went off without a hitch in Montreal and Regina is raising quite a fuss at the Canada Science and Tech Museum in Ottawa. "Sex: A Tell-All Exhibition" doesn't hold back in its graphic descriptions of the sex act, complete with audio and mood lighting. In keeping with the interactive theme of the museum, visitors can push buttons on the "Erecto-matic" to learn how a penis functions. Perhaps the most upsetting aspect of the exhibit for members of The Canadian Institute for Marriage and Family is the exploration of casual sex, anal sex, and same-sex couples. The Museum has responded to requests to yank the exhibit by raising the minimum age of entry from 12 to 16.
