DFK is a must for me. Having said that, I understand that some girls don’t offer it, for a variety of reasons. So I don’t push for it with an SP that I see for the first time.
I have proper hygiene, brush my teeth, use mouthwash, etc.
That’s why I repeat with my ATF and a few other regulars. They offer DFK, a true GFE experience, and we have good chemistry. I rarely see a new SP because it seems it to be hit and miss (maybe lack of chemistry, too transactional, non-GFE, etc). That’s why I prefer to repeat, why change something when I pretty much know I’ll have a good time!
