FK

FK stands for French kissing, and it appears on listings because it is one of the things most commonly assumed and least commonly stated.

Why it has its own heading

Because it is genuinely optional. Plenty of companions do not offer it, and finding that out at the door rather than on the phone is a bad start to an hour.

Having it on the profile removes the guesswork entirely, which is the whole argument for listing anything.

What it usually goes with

It sits close to GFE in practice. The two are not the same thing, but a companion offering the girlfriend experience will almost always offer this as part of it.

It is also one of the clearest signals of how an hour is likely to feel. A companion offering it is generally working at the unhurried end of the scale rather than the transactional one.

What it costs

Nothing extra where it is offered. It is an ordinary part of the booking rather than an addition to it, and any listing pricing it separately is unusual enough to ask about.

If a profile does not mention it

Ask on the call rather than assuming either way. It is one of the things frequently offered and rarely itemised, and the question takes five seconds.

Take the answer as final if it is no. This is not a service anybody negotiates on.
