If I can jump in here;
I see no reason the church should be led any differently than the household but, in the household, is the man really the absolute head? I thought both parents together were the head of the household and needed each other and a strong marriage in order to be good parents and have a stable/prosperous (those aren't the right words) family. And, that's what makes single parenting so hard and that's a major issue of homosexual families, right? Now, yes, wives are supposed to submit to their husbands but, it's not like 'husband' > 'wife' > 'kids', is it? It's more like this diagram. V
Now the husband seems to have more authority but, that's only because his traditional roles are more... 'authoritative'. The wife's leadership roles are just as important, they're just different. Men and women were created differently - each with their own inclinations and disinclinations but, they fit beautifully together like puzzle pieces. Why should the church be any different? Yes, men will tend to be naturally inclined towards teaching/doctrine/administration but, aren't encouragement/counseling/relationship building just as important of a part of the pastorate? So, don't churches with only a male pastor have a lop-sided triangle? For that matter, don't churches with only a female pastor? The great thing about the way God created men and women is that, while we each have our shortfalls, the others' strengths tend to fit into those gaps. We need each other - in life and in ministry. So, if you ask me, churches should ideally be pastored by married couples who work as teams and general ministries (unless they're geared towards a certain gender - i.e. - an unplanned pregnancy counseling center) should have both men and women in leadership positions.
As for your original question, TKD, I don't think there's much you can do. Generally teenage guys in the church who are lacking initiative aren't going to be very open-eared to criticism from... their female peers. I think that 'encouragement of men to grasp their role' is better done by other, more mature, men. But, also, don't feel like the only thing you can do in the church is help men. In the body of Christ, we should all pitch in however we can.
