Most Helpful Guy
If I am attracted to a girl and I sense that she is comfortable with me, I will try to give her a goodnight kiss on the first date. I want to establish, at the earliest opportunity, that I am not looking for a platonic friend. But I would not do it if I sensed that she would not be receptive.
You should never kiss someone to whom you are not attracted because it sends the wrong message and you are only encouraging the person to continue with other romance/courtship behaviors. If a guy starts moving in for a kiss and you don't want it, turn your head so he kisses you on the cheek. Most of us guys know exactly what that means.
