Are you implying that ALL teenage girls are beautiful and once they are no longer teens, they are no longer beautiful?
Clearly not. We all know that some boys and girls are butt-ugly and for girls, their youth can't make them attractive. What I'm saying is that our brains are wired in specific fashion and youthful look translates into sexual appeal. There will, of course, be variations in play. The truth of the phenomenon isn't found in single-instance tests, it's found in the patterns which arise from multiple tests. Take a random sampling of 200 women who are 29 and take another sampling of 200 women who are 21 and ask a random sampling, a huge sampling if you want, of men of all ages, to rate the women in attractiveness. You'll find that there is a strong correlation between youthfulness and attractiveness. Repeat the experiment and drop the ages of women, say to 26 and 18. You'll see the same pattern. Keep dropping the ages and
eventually the pattern reverses.
Are you also suggesting that some women don't get more beautiful as they age?
Sure they do. As noted above, there is an apex that has to be reached. Climbing upwards from 15 to X age, the girl gets more beautiful and then after hitting X she gets less beautiful. That age, X, is going to vary with individual women, but repeat the tests above and you'll derive a group mean.
We can all have opinions, but are they self-serving and ego-protecting or are they tested against reality? Women offering opinions on beauty, as seen by men, is as suspect as men offering opinions on what women find attractive in men.
You either have it or you don't (it's also EXTREMELY subjective).
Not really that subjective at all, actually. Sure, there will always be outliers, but follow some of the links on that page and see how these issues are validated with experimental tests. It's hard to train people to find beautiful what they once thought was ugly.
There are all different looking, shaped and sized teenagers, just as within any age group.
Absolutely. That's not the point though. What's in play is the odd developmental stage of adolescence and into young adulthood. The proportion of body size to arm size, to head size, facial symmetry, skin elasticity, etc. The shape of the face as it is maturing. At certain stages of development/aging the features are more attractive than at other stages. This applies to all the different looking, shaped and sized teenagers.
If you are referring to women who are over 40 and perhaps showing signs of their age, I don't think that men necessarily find that "unattractive" or a "turn off" either. It all depends on how well she has held up I would think.
Over-40 is long past apex. This is like men telling themselves that "a potbelly isn't a turnoff." What men find attractive or a turn-off is both objective and subjective. Most men who are 40 couldn't catch the interest of 23 year old women. They'd love to get them in the sack, but very few of them can. They target, or find attractive, the women that they can match up with. This process is, of course, moderated by factors which make relationships more enticing - the woman is more mature, they have more in common, she's not as idealistic anymore, she's not as clingy, etc. Whatever makes for a better match. That though is a different issue than how beauty is judged in isolation. As a general rule you can't go wrong with "younger is more beautiful."
This of course sets up life's great practical joke on women. Men, as they age, will continue to date from a pool of women which encompasses younger and younger women, so their pool of women keeps increasing. A 30 year old man has a larger pool of potential mates than a 23 year old man. Women, as they age, begin competing for men with younger women, and so the competition increases and they generally prefer not to date as age-disparate as men (think trophy wives).
Also, I would think that sometimes the little girl baby faces might be a turn off for SOME men at least. Some men might like a more mature looking female.
I'm not sure what you mean by little girl baby faces. Yeah, actual little girl faces don't turn on the sex attraction in men's minds. They're little girls, after all. That's not what you mean though, is it? Why not find some examples and post them and get men in this thread to respond. Or start a new thread. It would be an interesting experiment, especially with an anonymous poll.
Men WON'T find mature women more sexually attractive than young women. Not in a test of sexual attractiveness alone. For relationships, they'll bargain and convince themselves, but if they could get a Genie and 3 wishes, they'd likely construct for themselves a younger woman (we're no longer on subject here (15-17) and now we're talking actual women, not girls) in appearance with the personality of an age-appropriate woman.
