you make a good observation, but as the replies mention, it's likely a more nuanced reality than just gender. Id agree that at baseline a male gets certain crude roles thrust upon them, but i want to say it's not unreasonable to just not... accept them. yeah it may be uncomfortable, but really, like if your sister is cool with all these perks, i think a male is personally not gonna be cool with handouts due to his own machismo, it's not anyone else's machismo, it's the person's.
i know this is all enculturation, but same for the girl, when it comes down to it, it's our choice. i say, as a man, be vulnerable, ask for help. all good.
