There's not a real analogue I think for men. Some women put more stock into their chest than others. You spend enough time around them and you start to pick up on it, but they will rarely come out and say it. So that's why it pretty much has to be a wife/girlfriend.
It's not always fat chicks but it usually is women that have nice racks. Men can gauge their manliness with dicksize. But it's weird, too, because even flatchested girls will buy into it every now and then. Where a small dicked man will just become a banker. O burn, lithose, oh burn.
There is an entire world of boobie appreciation that men are not forbidden from ever knowing, but is simply outside of our perceptual range. AND THAT'S BULLSHIT, MAN.
I guess maybe there is sort of a male analogue with swoll bi/triceps. But it's not a very good analogue. About as close as we get I guess.
