He Said What - "Blast From The Past" -Why is it hard for men to open up?

For some men, talking about their past childhood can be like pulling teeth especially when talking to their children. Why might this be difficult to share? Is it because it equals them being vulnerable and transparent? Or is it because they feel someone might throw whatever is shared, back into their faces later on? Either reason, when you open up and talk about your upbringing, you allow that person to gain a better understanding of you. But the question is, do you want them to?
