The Art of the Kiss in France - La Bise

In general, gently touching your cheek to your recipient’s while pursing your lips and making a kissing sound does the trick. In Paris, you  start with the Left check (of the other person)  to check and yet in other parts of the country you start on the right!
If not sure, wait for the other person to start first.

. How many kisses: It depends on the region, so observe the people around you and follow suit. 
Here is a map showing regions and how many kisses to plant.
