In the same way you power through taking care of your kids, not because you enjoy it but because you prioritize their well-being, how likely is it that moms are generally doing the same? It seems to me like men have been historically avoiding this child-rearing responsibility, moreso than women enjoying doing so.

I can tell you that my wife and I are both exhausted of taking care of them 24/7. It is not something we do for funsies.
