I agree with mansion that it is just his hormones kicking inside the boy, After he has satisfied his hormones thirst then "Prem ko bhoot uttrainchha" I also agree with tshetensherpa about "live and learn", give guidance but to listen or not to listen is his problem. But at that age Hormones voice is louder and effect is stronger then your words of wisdom and experience. It is like when you gotta go then you gotta go.
