Hi Ann,
Neck and kissing would be the main symbols in this dream.
The neck can symbolize so many different things - it connects the intellect and the heart. Having a stiff neck could mean difficulty accepting certain situations. Or maybe you are "sticking your neck out" and risking something.
Kissing generally symbolizes connection, and since it was on your neck - the center for the throat chakra and seat of communication, it could represent communication with the self.
What I think is important to pay attention to in this dream are:
How do you feel about this guy?
How do you feel about the kiss?
What were you feeling when you wiped it off?
Those are just my thoughts, and I hope they can give you a good starting point
