No, it wouldn't happen to a man!
In fact (based on non-scientific observations) men's stupid behaviour is often excused by being "young at the time", even when they weren't that young! I think men aren't expected to be mature enough to take responsibility for their actions until they're around 40.
For women and girls it's around 13 I think...
