Men's minister Edwin Louis Cole used to say, "Manhood and Christlikeness are synonymous." His point was that Jesus is our example in all things, including manhood.
I'm not saying that the picture of Jesus we have from the Bible tells us everything about manhood, but rather that it gives us more insight into what manhood is really all about than any thing or anyone else. There are, of course, other great examples of manhood in the Bible - Abraham, Moses, David and other heroes of the faith - but none of them gets close to the perfection we see in Christ.
One of the difficulties with this view is that Jesus circumstances vary from ours in all sorts of different ways - he didn't marry or have a family for example. However, the principles that he taught (both through instruction and example) apply to all our situations. For example, his actions towards his disciples illustrate the kinds of behaviour he expects us to show our children. His directive to love others as ourself applies to our relationship with our wives.
