There is no duty we so much underrate as the duty of being happy ©R.L.Stevenson

Girls, ladies, women, mothers during their life repeat for thousands of times the same ridiculous phrase "a man must". It does not matter what the "duties" of a man are, in the opinion of a woman, he is simply obliged to fulfill all the whims of his madam, because she is a goddess, clever, beautiful and, in general, the pinnacle of the ideal.
Stupid girls. A man is not obliged and doesn't have to. The only variant when he is obliged is when he borrowed from a bank or from his friends, acquaintances and so on.
In all other respects, the representatives of the stronger sex have the right to: manifestations of care, love, the opportunity to consider themselves an alpha male, provide for his family. Women with their demands kill in men all the desire to be their super-heroes, as it turns into work, and the work puts a certain scope, narrows the flight of fantasy.
That is why he has no desire, and it's easier to lie on a sofa with beer, and the romance has gone somewhere, and the princess has turned into a typical grumbling housewife.
Conclusion of the day: a man can not and should not be forced to do anything, but on the contrary - you just need to give him the opportunity to show his inner hero. The result is a happy couple of the hero and his princess ♥
Do you think a man has responsibilities to the weak sex, which must be a priori carried out? Or are you for equality of the sexes?
