Weeeelllll, I don't want my woman protecting me. Nor do I want a sugar mama (or do I?). And sure, I wanna feel loved and cozy and comfortable, but "safe" in regards to my self-preservation from any outside physical or verbal aggression, that's on me. And on me to provide that. Or at least in my vision.
I had a big bad boxing coach with 3 kids and a wife tell me once that when you take on that role of family man, you, in a sense, become their bodyguard. Not that there's people trying to assassinate you, but there are dangers out there.
I don't think that woman=man. Not that one is superior to the other, both genders have unique gifts, and are equal, but in different ways. Sure, you can get a wimpy guy that's dating a female boxing heavy weight, and makes all the money, but I'd say that's the exception.
Virtually all species of animals, especially social ones, have specific roles that are true throughout generations and in different regions. Lions protect the pride from the threat of other male lions, and the lionesses hunt, for example. We're not lions, but that is one of MANY examples. Chimps and bonobos have different gender roles, as do baboons, wolves, jaguars, etc. etc. But within a particular species, it's generally the same.
