In sections 51A, 52, 53 and 53A “prostitute” means a person (A) who, on at least one occasion and whether or not compelled to do so, offers or provides sexual services to another person in return for payment or a promise of payment to A or a third person; and “prostitution” is to be interpreted accordingly.

In subsection (2) and section 53A, “payment” means any financial advantage, including the discharge of an obligation to pay or the provision of goods or services (including sexual services) gratuitously or at a discount.
