Daplaoke,
Because none of us were flies on the wall while you had this encounter it is very difficult to answer your question. I have often wondered what would happen if, like Jeff Goldblum, I can turn into a fly and watch one of these reported encounters.
As you gain more experience you will figure out YMMV/chemistry factors. One thing that greatly impacts on such factors, in my opinion, is the ability of the client to communicate in a way that puts a girl at ease. Girls want to feel that they are with a guy who is “normal”, and doesn’t creep them out. I have a very serious looking natural mug on my face and I learned early on in my “sexual career” (LOL) I had to develop better communication skills and demeanor and body language skills, because women meeting me for the first time would tell me I am very serious looking. If you can project that you are easygoing and affable it really, really helps in building chemistry and comfort. I have gotten better at it since I started out, by a lot. Experience really really is a great teacher on the issues you have raised. Of course, no matter how smooth a talker you are or how well you put a girl at ease, chemistry will not always be perfect with certain ladies. But language, demeanor, and being able to project a gentle, easygoing/affable nature will greatly enhance the chances things go well.
