I very rarely cry. Most of my male friends I think see it that men shouldn't cry and so don't, though my gay friend cries whenever he feels the need (invariably more than me).
Personally I don't cry though I know it's socially acceptable for me to do so. In the same way, I'm sure some men don't. My female friend cries a lot (stupid amounts) which irritates me, I suppose.
Some men, meanwhile, suppress their feelings so they don't cry, because they think it's unmanly. I don't know whether my gay friend is naturally more in touch with his emotions anyway, or whether he believes it's more socially acceptable to cry because he's gay.
