The emphatic curve in these ladies’ backs, making their buttocks more prominent, resembles lordosis. Wikipedia considers whether this ancient mammalian posture has a role in humans here.
I have written at this blog about why certain female body parts have such appeal for men. In reflecting on female legs, my feeling was that heels work mainly by accentuating curves. I wonder if the real fundamental “sexual releaser” for men might simply be curves. In lordosis. With breasts. With legs …
Are long, gentle curves the most attractive? Like the Eiffel Tower:

Is the “Why?” of it so important in the face of it working so well?
Posted by Julian O'Dea on October 23, 2017 at 7:36 am
Well, I am sort of a scientist, and I like to understand.
I have ordered a book on the mathematics of body curves. I suspect the ideal curve on a woman is a gentle curve. Or at least somewhere between a straight line and a circle.

For me, the ideal curve on a woman is that curve I see when my wife looks a me and sashay’s her butt.
Wife Goggles are good. 🙂

Wife goggles are indeed good. I still have mine on.
Mine doesn’t do the sashay thing. She does the “look at me getting my bra on” thing and “my legs are still good” thing.

I actually noticed this on one of the (very few not fat) moms on at the football game yesterday. I wonder if it also makes them look more “receptive”?
Posted by Julian O'Dea on October 23, 2017 at 11:21 am
That’s one theory. But if it does have that effect, it implies that humans have retained some ancient mammalian sexual signals. As I have written previously, it is possible that rear entry is still a natural part of the human behavioural repertoire. Maybe lordosis is tied in with that.

If you’ve ever seen the movie “Quest for Fire” you might remember that the female from the more advanced tribe taught the male from the more backward tribe about missionary position sex.
Anyway, its really a good movie if you’re interested in what looks like reasonable depictions of early man. If not, you might try Teenage Caveman, or Ringo Starr’s Caveman movie.

Both ladies are quite slim, and are hyper-curving their backs to make their behinds look like they’re curvy AND as if they’re receptive to sex (why pick one?). So, it’s flirtation and flattery. Similar flirtation to bending over in a low cut dress and smooshing your breasts together with your arms a bit. Women’s clothing offers a lot of options for making un-curvy girls look a bit curvier, and women traditionally flirt by displaying the goods. “Come and get it… ”
Thinking of the opposite, do you remember the foo-foo rah when Kiera Knightly wore that Chanel suit (cut to make one’s waist look tiny) and everyone fainted because of how thin she appeared – though it was all fool-the-eye? http://i.dailymail.co.uk/i/pix/2014/03/04/article-2572803-1C0737FB00000578-112_634x917.jpg

I suppose, Hearthie, that the interesting question for men is how much of this is conscious, and how much is semi-conscious and even instinctive.
Posted by hearthie on October 23, 2017 at 10:18 pm
Quite a lot is conscious. Sorry. Because there are subtleties that the youth just don’t … it’s sad, really. They’re so in your face, when just the turn of an ankle would do the job. You don’t need to Kardashian to play the game… :p

Oh, yes. I know. Sort of. My wife was asking me recently about why I first asked her out (it came up for some reason.)
I told her it was because we had had a fairly heated debate at a party and I thought, why not, things can’t get any worse. And I seem to recall that she had also told me a slightly erotic story (about her swimming naked at a house she was minding, and the boy next door “perving” at her.) That had intrigued me.
To this day, I don’t know to what extent these things were ways of getting my attention. I realise they were more things said, than flirting with her body itself, but no doubt that can work too.

Much starts out instinctive or accidental, and then you see the effects… :p I know a couple of ex-strippers quite well, and they know how to grab a man’s attention, fully clothed and offering nothing but a smile. Educational.

Who doesn’t know by now that the Russian dating sites are all scams?

[…] I wrote about lordosis here recently and speculated on the more general role of curves as sexual releasers. […]

Jessica Alba provided a nice example of lordosis a while back with her famous ‘bikini pose’ which launched a thousand imitator starlets.

Man. I like slim women, but she is a bit too skinny even for my tastes.
