How do you greet members of the opposite sex?

For instance: in some countries, men and women air-kiss each other twice. In some countries, it’s three times. In America, it’s common to hug someone you know decently well. Sometimes it’s just a handshake.

I’m very curious, as I have recently had some awkward interactions where, for instance, I went for the Dutch standard of 3 times with someone from a country who didn’t expect a third ‘mwah.’

How do you handle this situation?
