Hmmmm...I think if it was a really genuine concern for lots of men, then they would be in other low status caring jobs that are mainly staffed by women and they'd be stepping up far more with the unpaid caring roles that women take on as well.
They seem to get over it when it comes to things like sports coaching where they have a real interest as well, so I think there's often a bit of whining going on.
Not in the case of your partner, UBW, but as a general rule.
