The Development of Secondary Sex Characteristics in the Human Female between Ages of 13-16, and to a Much Lesser Extent to 18-19

16+ is another way of saying mature females because females have a full sexually mature female body by that age.

Before that age from 13-15, the female body is developing and changing from a girl’s body into a woman’s body, and in certain ways, it is not fully sexually mature.

The curves that men like so much in a woman’s body, mostly a consequence of enlarged hips, buttocks, and breasts, develop over this period.

13-14 year old girls often have stick-like straight bodies similar to a boy’s body. For this reason, a lot of men find them not fully attractive. That stick-like body is a killer at least for me and some men I know.

A 15 year old girl is just odd. Frequently their bodies simply appear out of sorts as if they are not developing properly. Their bodies often look “awkward.” Of course, this is around the age that teenagers are often “awkward” anyway, and if you approach one of these “awkward”-looking 15 year old girls and try to talk to her, she will often give you a response that is rather “awkward.” I was on Kik a while ago, and a 15 year old girl messaged me apparently wanting to talk dirty. I talked to her for just a tiny bit with no serious dirty talking before I blocked her out of fear.

Nowadays they will put you in jail for the crime of “talking dirty” to a girl that age, which is a ridiculous crime in my opinion. Anyone can say anything to anybody within reason. The whole idea of crimes called “illegal talking” is perverse and bizarre. However, the way she approached me in a flirtatious manner was also rather awkward. She didn’t even know how to talk dirty in the few sentences we exchanged.

13 year old girls still have what my friends call “those little girl faces,” and they and I both regard it as a turnoff. My Mom said it’s probably “baby fat” that is present in the faces of all little girls. The baby fat probably starts to go away around age 14.

If you look at a grown woman, her face is rather bony. It is not bony in a bad way, but it is quite hardened. The most beautiful women have prominently bony faces with “sharp” and well-defined features. Noses and upper cheekbones are some of the important bones in woman’s face in terms of beauty. In fatter women, these bony features tend to be covered up with fat, which can make fatter women less attractive, though I admit there are some fat and even very fat women who have absolutely gorgeous faces.

During this period, the breasts often grow larger, and there are also changes in their appearance that are hard for me to quantify, but I will only say if you have seen enough of them, there appears to be something “wrong” with the breasts of 13-16 year old girls, and I don’t mean in just size. It is something about their general appearance and also I believe the appearance of the areola. But I’m not an expert on breasts, so I’m guessing here.

Pubic hair growth is complete by age 14 in the female, but it does grow a bit more to areas that are normally shaved nowadays to the inner things, the perineum, the area around the anus, and even in some cases above the public mons towards the navel in a long thin line.

These are called “happy trails” and back in the day (the 1960’s and 1970’s) you saw them occasionally. I remember one of the female lifeguards at the pool we went to used to have one which she sported in proud and showing manner. My eyes always drifted right to it as a teenage boy, and she always smiled at that. Nowadays it would be regarded by most younger men are horrible and disgusting. Nowadays they’d probably ban a teenage boy from a pool for even looking at a young lifeguard’s happy trail.

The vagina and anus probably grow between 13-16 in size and shape as does the rest of the body. As female height is complete by about age 16 (there is another inch or two of growth that may occur at age 17), the organs of the body should all also be fully developed by 16. In Yemen, they often marry girls at age 13 to grown men. I was not aware that sex with between men and girls that age was dangerous, but there are reports that some of these girls die with complications from having sex with these men, possibly because hard sex with a large male penis is too much for a 13 year old girl’s vagina to cope with. But don’t quote me on that.

Also, 13-15 year old girls have anuses that are smaller than that of a grown woman. In my lifetime (though it has been 20 years since my last such conversation) I have talked to girls around that age about anal sex. Some of said that they did it, but they only liked smaller or “thinner” penises. I’ve never heard a grown woman say such a thing, so this implies that in girls this age, the anus is smaller than adult size.

Of course it becomes increasingly more difficult for girls to get pregnant as we descend from 15 down to 13 years old. Females are not fully fertile until age 16. This implies once again that females are fully developed at that age, not only in organ size and height but in other ways too.

Females do grow a bit after 16-17. Around ages ~18-19, females hips widen quite a bit. This is done in order to be more able to carry a baby. Girls under 18 have hips that are not really wide enough to carry a baby, hence there are many more birth complications with girls that age, with consequences for both the girl and the baby.

This is why girls around age ~16-17 have bodies that seem to be the perfect female body, which in nature barely exists. They have the fully rounded body of a female with full female breasts, but their hips have not widened yet. So you end up with skinny girls who are very curvy. It’s a male dream. However, this dream woman is an aberration, and she is not even very physically or genetically fit. What you are seeing is a woman who is not yet developed enough to carry a baby, so it is not natural or normal for a female to be this way.

The ideal female for males is an abnormal female such as barely exists in any full-grown woman. The truth is that curves and big breasts go with heavier women. Thinner women tend to have smaller breasts and less curved bodies. Some almost have the stick-like figures of boys or 13-14 year old girls.

You love big tits but you hate fatties. You’re out of luck, pal. You love thin women but you hate small tits. Sorry guy, your model’s been out of order forever.

You got one or the other. You want big tits? Fine, accept a little fattiness. You want thin bodies. No problem, but smaller breasts come with that model.

The male ideal, a thin but curved woman with big breasts, is basically a nonexistent creature, though some 16-17 year old girls look this way, but that body is abnormal and will function poorly in some ways.

  1. I do not believe the story about sex being dangerous for 13 years old girls. One of my friends started to date a girl when she was 14, and I know for a fact that my friend has a massive schlong. I have to admit that I envy his massive dingdong.

      1. I’ve known several 13yo girls who fucked grown men no problem. Once on a train I got 4 fingers in a 13yo up to the knuckle and she enjoyed it. I think 8yo girls can probably take a normal size adult dick without too much trouble. I’ve seen girls that young naked in LS models stuff and it’s surprising how “open” their vaginal holes can be.
