umm..well first of all, it doesn't really make sense in english. but what i understand from this is that you're trying to say, 'i want to kiss' in that case, it would be, 'quiero besar' but if what you mean is 'i want a kiss', then in spanish it would be, 'quiero un beso'.
kiss in Spanish is beso.
besar= to kiss besa! = kiss! (as in the song 'Besame mucho' (Kiss me a lot))
beso
Kiss your girlfriend would translate to 'un beso a su novia' in Spanish.
Dame un beso would be the best way to say "Give me a kiss" in Spanish.
Besandose
Translation: ¿Puedo besarte?
the answer is: kiss my butt
You can say "Quiero besarte."
un beso
Translation: ¿Puedes besarme?
neck (part of the body) = cuello
