That is not self-control. It is emotional repression.
Of course, there are emotions that are notably exempt from this need of "self-control", and they are the most harmful and directly destructive ones - emotions of aggression, lust and power, and especially the intersection of these fields. Indeed, men are encouraged, indeed shamed into, indulging these emotions without restraint. Their ideal of a man is a brutish skirt-chasing rude thinskinned pompous domineering egotistic ruthless reckless inconsiderate controlling violent abusive predatory arsehole.
And then, they have the audacity to claim that men are innately less emotional than women and consequently superior.
In the end, machismo really is nothing but a really nasty and toxic mindset that really needs to die.
