These fall into a number of categories known by various euphemistic names, such as soaplands, fashion health shops, and pink salons, with the term "health" commonly being a euphemism for sexual services. These businesses typically operate out of physical premises, either with their own employees or freelancers such as call girls , who may operate via Internet dating sites known as deai sites Internet dating sites or via delivery health services.
