When did you become a "man?"

On the Journey to Manhood website, I asked the following question to men from all over the world:

What was THE moment in your life when you knew, for sure, that you had become a 'man?' Who was there? What was done? What event, action or ceremony took place so that you knew a line had been crossed and you were now a 'man' (or at least more man than boy)?

If you don't have a good answer, why not?

You can read men's responses on the JTM website.
