You only need to have seen the display put on by Patrick Kielty who, over several hours, sobbed himself to sleep on the first night on the Sport Relief's £1,330, 000 sponsored bike ride to know that the answer is NO.
He proceeded to sob after every little ride he did thereafter (between bouts of drinking alcohol).
I am very uncomfortable with men sobbing unless there's a very good reason for it, which would typically involve personal loss or some tremendous achievemnet / high.
I was very surprised by the out-pouring of grief after Princess Di died.
