FS stands for full service, used in commercial-sex advertising for full sexual activity as opposed to a listing limited to other acts. It is shorthand rather than a defined service, and what it covers is agreed directly in advance.
Initialism of full service (“full sexual activity in prostitution”).
This is advertising shorthand, and the distinction matters more than it looks. An expansion is not a specification: knowing what the letters stand for tells you the emphasis being advertised, not what any individual offers, on what terms, or whether they offer it at all. Two listings using the same letters may mean quite different bookings.
What ‘full’ is taken to exclude is the part that varies, and it is not settled by the term. The word marks a contrast — this listing is not limited in the way some others are — without saying where the limit falls for the person using it.
The same adjective also appears in a broader sense, in the initialism FSSW: full-service sex work, or a full-service sex worker. That names a kind of work — as distinct from stripping, camming or domination, where the worker does not have sex with clients — rather than an item in an advertisement. The two uses are related but not interchangeable, and reading one as the other is a common mistake.
Terms are agreed directly and in advance in every case; we do not publish rates as fact anywhere on this site. Country rules differ — see our legal status hub.
Frequently asked questions
What does FS stand for?
Full service. In commercial-sex advertising it signifies full sexual activity, as opposed to a listing confined to some other set of acts.
What exactly does full service include?
There is no agreed answer, which is the honest one. The term marks a contrast rather than drawing a boundary, and where that boundary falls is the individual's to state and to agree in advance.
Is FS the same as FSSW?
Not quite. FSSW — full-service sex work or full-service sex worker — describes a kind of work, as distinct from stripping, camming or domination. FS is an item in an advertisement. The adjective is shared; the two are not interchangeable.
