When contacting an escort and there are no reviews I will always ask if she does DFK and I will describe explicitly what I want because DFK is the most important part of the session. Just asking for deep french kiss with tongue is very descriptive and offers no margin for error. However some escorts get offended when you are explicit and some will just cut you off.
All of the styles in the video mean DFK to some people. Saying deep French kissing with tongue doesn't tell me if your tongue likes The Reptile or The Spin Cycle. But I understand what you are saying and I guess there's really not much more you can say. But it's just something I have learned to manage.
Tbh I have turned down appointments when someone put a lot of emphasis on DFK, lots of it and that it was the most important thing for them. In those situations, I just didn't know if I could provide what they had in mind and didn't want to risk an awkward, disappointing experience on both sides, so I declined.
In reality, I may have totally enjoyed their version of DFK but I couldn't know that. And I just really can't promise reptilian tongue kissing as main feature. It's just the way it is. Makes me anxious so I just avoid it so they can find someone who doesn't mind.
But I get that it's not really possible to describe more and that most providers probably feel differently about it than I do. One of my quirks, maybe. Lol
