I have been doing this for years, when I meet up with a fwb I usually greet with a hug and kiss (like you would a girlfriend) but last night a new girl that I've been messing around with acted a little weird when I did it. She kissed back, but she hesitated and everything was back to normal after today.

That got me wondering if it's not cool to greet with a kiss? What's your thoughts, reddit?
