You are in for a challenge because society is designed to make people (all people, not just guys) into pussies. It's designed to make people "domesticated" to the system so that they don't try to do anything in life which they can't predict for: so they are easily controlled and don't rock the boat which the social elite control.
The behavior that marks AFCism and people in general exhibit is that they "Accept what life gives them" rather than the more masculine approach of "I want something >> How do I get it? >> Taking action to get it >> Get it."
The public school system is going to do a very good job at making your boys into domesticated little pussies, so that they do what society tells them they should do (Check out John Taylor Gatto's website and his book the Underground History of Public Schooling or something like that which is available to read free on his website).
In order to avoid your boys becoming complete pussies, they need to set goals of their own choosing and then following them through to their completion. They also need to see you setting goals and accomplishing them, preferably not superficial goals like, "I want to buy a lexus or an HD TV" which are material goals and not real goals. The goals they/you should be trying to accomplish are goals which make them a more powerful, well-developed person through the process or gain them experiences and enrichment in life not I want to have X, where X is a particular object.
One of the common themes in becoming a DJ is personal development, so that they gain the skills to get women, self-confidence in their personal achievement, and ***** in the process. This idea should be molded into their lives, because that's what masulinity is: "I want something, I'll figure out how to get it then I'll get it." If they are used to accomplishing goals, then when the time comes they will want ***** or a girlfriend and they'll try to achieve it. They'll fail some in the process and become men along the way.
Don't let them do too many passive activities where they don't experience life, but instead only observe it, like sitting in front of a TV most of the day, or on the internet all day, or whatever.
I wouldn't worry too much about them hanging out with girls because if give them exposure to masculine concepts of life they'll naturally enjoy those things because men gain pleasure from building towers and conquering life.
