I haven't cried due to physical pain since I was like six, and I can still remember the last time I cried due to emotional pain -- four or five years ago when I got dumped by a girl I loved.
It certainly helped then, but I agree that it's tough for "manly-man" types to be comfortable with crying. It just gets ingrained into us from childhood that real men don't cry. I really don't know how much it would help you out now. :dunno:
