A girlfriend experience (GFE) is a commercial experience that blurs the boundaries between a financial transaction and a romantic relationship. It ranges from a transactional sex relationship to a client paying a prostitute to pretend to be his girlfriend during the session. Within the sex industry, GFE is a common term for a sexual encounter in which both the sex worker and the client are willing to engage in reciprocal sexual pleasure and some degree of emotional intimacy. A "girlfriend experience" generally involves more personal interaction than a traditional call girl or escort offers. There is a focus on not just having sex, but also having more of a comprehensive experience. The details vary widely from person to person. In the field of sex work, sex workers impart a sense of authenticity in order to make the experience more pleasurable for their customer, as well as to make the outcome more lucrative for themselves. Paying for any sexual act, including GFE, is considered to be a form of prostitution regardless of the type of service involved. Because of this the legality of GFE varies from place to place.
If the sex worker is male, the service is called a boyfriend experience.
