My opinion is that it's passionate, open mouthed, tongue action! Some guys are like 13 year old boys that slobber your whole face and stab their nasty tongues in and out. I've had some great kissers in bookings.
It's a mystery to me what you know who's version of dfk is or anything else they talk about for that matter x
Yeah your idea of DFK is the same as mine but some people take it too far.
It's like asking someone what the definition of GFE is, that's such a grey area too as everyone has different ideas of what they mean.
I market myself as GFE because I am the complete opposite ends of the spectrum from PSE but I've had a few guys think that bareback, CIM, swallow etc is part of GFE cause that's what your real life girlfriend would do.
I suppose no matter what service you offer, there's always someone who wants to take it too far. Deep throat is a perfect example......when giving oral, I'm happy to go all the way down on it (after all that's where the sloppiness comes from) but I don't have deep throat ticked on my profile because there will always be someone who thinks he can come in and fuck my throat to the point of actually chocking on it (which I don't mind a turn on in any way, shape or form) or to the point where your actually vomiting!
