I am into the whole GFE and agree that it lacks intimacy when FK is tentative at best. However, there was one particular occasion, early in my punting days, when I visited a Lithuanian(at least that's what she said) girl in Athlone. She was beautiful, with a great body and just enough English to communicate that we could do anything except kissing. While the encounter lacked a certain amount of intimacy, on this occasion the sex more than made up for it, as I got two goods rounds in during the hour.
I think it should be a bit clearer on the profile that the lady provides FK, but she should also have the prerogative to decline, if the hygiene standard of the client is not acceptable to her. The client still has the option of leaving if he is unhappy with her decision.
Thankfully, I have managed to meet quite a few ladies who excelled at GFE & DFK and have had many a very happy encounter.
