Can guys' feelings hurt even when they don't show it?

A lot of guys put on this tough guy front that nothing ever gets to them and they don't care. Is this really how they are or are they just as sensitive as everyone else but they don't show it? I know that society expects guys to be emotionally strong but does that mean you guys have feelings like we do and you have to cover it up, or you just don't care by nature?
