Promised lessons by ``teachers of repute,'' students of both sexes who pay the sum of 1,500 Belgian Francs can expect courses in the laws governing prostitution, hygiene, accounting and management as well as sexual techniques, said Veronique Grossi, the coordinator of the Payoke organisation.

Payoke said its courses were open to those already plying the trade or to those who aspired to become prostitutes. ``We have noted that those who really want to practice this trade do not know where to seek advice,'' Payoke said.
