DALLAS (AP) — An upcoming sex exposition in Dallas that's billed as the largest of its kind in the U.S. is being criticized by a mayor who says it goes against the city's position on the exploitation of women.

Organizers for the three-day Exxxotica expo, which begins Friday, say it's expected to draw more than 15,000 people.

Chicago and Los Angeles have hosted Exxxotica in the past and its arrival in Dallas will mark the first time it'll open in the Bible Belt.

Mayor Mike Rawlings has sought ways to stop the event because he says it's exploitative. But city attorneys say Dallas can't deny the use of a city center just because of disapproval with the featured content.

Exxxotica director J. Handy says his expo is tasteful and often the source of misconceptions.
