Sexy School

Throughout history, erotic dancers have exuded a mystique, as if their tease held the secret to good sex.

That secret may be out.

At studios from Los Angeles to Miami, the striptease is being taught in exercise classes to everyday housewives, mothers and grandmothers. Hundreds of women are signing up for the so-called "fertility goddess" classes, with one North Miami Beach studio saying it teaches between 300 and 400 women a week.
