My step-daughter is very athletic due to her occupation. She lived with me, alone, for several months when she was just 20. She is quite beautiful for a Chinese girl, often wearing revealing clothing (pajamas, shorts, etc.) as well as sitting or reclining in very unladylike positions.

If I were a normal adult male, I would, to this day, lust after her. Yet, never have I had the remotest thought of romantic or sexual inclination. My wife knows of my pedophilic ORIENTATION so she didn't mind my step-daughter living with me. She knew I would not even think of an impropriety. I just can't think that way. She knew that. My step-daughter, however, does not know. Yet, as adult as she now is, I'm sure she has never had a thought of impropriety towards me. I'm way too ugly plus she has a new husband.

adult women lose their most girlish appeals so soon.

Hajduk is right. For me, if she had been in first grade, my wife would never have left me near her. She would have been right. But, let's look at her from a biological perspective.

Females of our species are responsible for biologically caring for progeny until several years after birth. To be biologically able to do this, females must change from being a child themselves. For example, their reproductive equipment (i.e., uterus, eggs, feeding glands) must be capable of hosting a developing human. While females begin life with all the Oocytes they will ever have, the rest of the equipment must be operational at puberty. This begins around 10 or so, these days. Of course, just getting efficient then takes a few years. While it is possible to begin gestation at her first menses, she is NOT very efficient at this time. To be fully efficient, she must have continued to develop for a couple more years. Say, she would be ready and efficient around 12 or 13. This, despite modern social thinking, is human reproduction as biology has set the stage. Religions and other social insanities are irrelevant.

Males, on the other hand, while hitting puberty at around the same age, are well aware of prospective females' bioligical readiness to procreate. Noticing that female breasts that are firm and sized enough to conduct child feeding, they are attractive to normal males that have passed their own puberty. So, too, are female hips that indicate the female is capable of passing a newborn's physical features from the mother's uterus to the outside world.

What are other biological markers that normal males look for in normal females? Things that indicate, basically, that the prospective human is, in fact, female. That is, human males should not be biologically interested in sexual reproduction with another male. The equipment just is not there. So what indications are necessary for a normal male to conclude the prospective human is female? From a distance, the length of her hair will be obvious... usually. Males with long hair seen from an obscuring distance, can be initially interesting to a heterosexual (normal) male until other male attributes become apparent. Surprise.

Upon close inspection, female breasts and wide hips are the first indications. Then, the pitch of her voice will become interesting.

But, returning to the quote from Hajduk's post, an elderly female will not be sexually enticing to a normal male compared to a young teenager. Of course, there are those abnormal gerontophiles that would be the exception, but that's not my point.

No matter the social philosophy of the NORMAL human male, they will find the young female teenager to be extremely sexually attractive. That's just normal biology. So, what is the statistical peak of sexual attractiveness to the normal adult male? Just a couple years after a female's puberty. Again, for a normal male. An adult female will subconsciously know this. Just as an elderly male regrets his sexually inefficient age, an adult female will also feel the regret unless she is busy caring for a human child. If not, she will do her best to indicate her sexual youth by covering up older age indications such as facial wrinkles, sagging breasts, and used uterine features of her abdomen.

Next, as any normal adult male will agree with, a female's arousal towards him will tell the normal adult male that a sexual encounter is possible with her. So, red lips and face cheeks (indicating being blood filled) are signs of sexual excitement. Wide irises in her eyes also express sexual interest by the female. (I can't recall the university lecture on the female's ears where I'm getting all this from, but the earrings bring a males attention to them.) Modern female facial makeup (painting, and skin smoothing, etc.) are all focused on accentuating (first) sexual attractiveness then (second) sexual arousal.

Unless a human male has deviated from the statistical norm of the Earth's population of humans, he will be intensely attracted to the post puberty female. Again, if he is a normal male and says that he is not acutely interested, he is either not normal or he is lying. The lie, of course, has a multitude of social justifications these days. Nevertheless, the lie is there.

So, adult women lose their most girlish appeals a few years after puberty. That's biology. Lying about it is sociology.
