I can recall seeing these types of guys at the Eiffel Tower a lot.
This will certainly not be an easy task but if you find yourself in a sticky situation with a French guy, then you have to build up the courage to tell them about the cultural differences when it comes to dating.
The talk could be interpreted the wrong way and could even scare the guy away, but if you're uncomfortable then it's something that must be done.
I swear only 10 minutes went by before the guy started telling everyone that my friend was "the love of his life." After that night he thought that they were officially a couple which was certainly not the case and getting him to stop pursuing her was quite a task.
If affection translates to exclusivity, then don't even think about having sex with someone unless you plan to being in a relationship.
Try to be gentle and calm when bringing the topic up.
Tell him that things are moving too fast and you're not ready to be exclusive.It's also not too common for two people to go out alone in France.Even a simple coffee outing can be interpreted as something more serious.Also as an American don't be disrespectful of their culture.If you normally enjoy being affectionate when you're in the dating stage, then you'll have to restrain yourself.It was pretty obvious what the guys motives were judging by their body language. They would serve the girls more and more wine but they wouldn't drink nearly as much.
