Sounds like your Frenchman does not have lines he has a personna and he lets you be in control. Us Guys including myself could take lessons. I think you hit on what many women find attractive.
Personally, this type of guy would turn me off big time. I mean, c'mon, he schmoozes women for a living....sounds like he's a male ho to me. What's the difference between a guy trying to sell his vacation spot or a car salesman? I would send a guy like this away in a nano second!!!
