Hey Wendy, I was reminded of an article I read months ago and saved in my work e-mail about this topic. The article was called "The Difference Between a Man and a Boy" and it was from the National Fatherhood Initiative website (you should be able to google it). It was an interesting article (I don't necessary agree with all of it, but it was worth reading), and there is also a book called The Demise of Guys: Why Boys are Struggling and What we can do about it By:Philip G. Zimbardo. I haven't read the book.
I don't know if any of this will be helpful to you, but I thought it was worth mentioning.
