on a second thought...
There were times when having wet dreams had you castrated , when caught red handed.
We are not so cruel this days.
I just invented new electronic device.
Lets take a dog collar and install on the neck of all youngsters.
Then one sensor down there.
When detect any arousal - electric shock will be send to correct incorrect behaviour.
Your 18 th birthday will be celebrated with removing dog collar, or sensor.
on second thought...
I think dog collar could be left. but sensor replaced with remote control dongle handled to your wife.
