Am sitting here wondering this too. Aside from DH going out to work and me logging on to write/study/research, we operate identically - we both drive considerable distances ferrying the kids or to work/conduct daily chores, we both garden, put the bins out, take crap to the tip, cook (DH from scratch, me less so), clean (though I now have a wonderful cleaner, so we both do less of this), we both live in trousers/jeans, wear flat shoes, walk the dogs, decorate (mainly me, actually), assemble flat pack-furniture (again, mainly me because anything Ikea adjacent transforms him into a grumpy arsehole). He uses Clarins moisturiser having nicked mine, I rarely wear make-up these days and can count on the fingers of one hand the number of times I have worn a skirt/dress in five years. We both love the theatre, classical music, live gigs, the arts, travel, our kids.
The only obvious difference between us is that he likes all forms of sports (just tennis really for me), I have long curly hair (but so does my 17yo DS) and I like a good G&T when he prefers a good beer or ale. [ETA… he obviously has a penis and I have boobs and a uterus, of course… but it’s not about the genitals, is it?]
At which point am I womaning to his manning? Or is he womaning to my manliness?
