Men are advised on what women find irresistible - what brand of perfume, what length of beard, how much muscle, what sort of music, what make of car, what style of clothing, what hairstyle, what conversational gambits.
Well, women are all the same, aren't they? They all respond to similar things, so you just have to get those things right and they'll be putty in your hands.
I must say, if I were a woman, I'd probably run a mile from a guy who's constantly tweaking his appearance and his possessions to make himself woman-friendly, rather than just being himself.
For that matter, long ago when I was still looking for a partner, I'd have run a mile from a woman who was clearly putting on an act for my benefit.
Men who're obviously "performing" for a female audience are very tiresome. Luckily most of my life I've worked with men who found such performing laughable and wouldn't be wondering if women might disapprove of their beard length. More likely they'd be wondering if women would find their political views feminist enough.
According to the romance pundits, I've probably done the wrong things all my life and alienated every woman in sight. Clapped-out cars, dodgy music, outmoded clothing, dumb hairstyle. None of which bothered my partner when I met her in 1981. She would certainly have high-tailed it from some smarmy Mr Pulling-Power.
But it seems plenty of guys still fervently believe in romance-by-numbers.
