This is a very hard question, if well the future and sociocultural interactions are hard to predict and many times could be wrong, but with the enough antropologic investigation comparing historical situations and current tendencies applied to this new context I thought is possible reach to an interesting answer. For this I will base this on the next question How could a human-descended race appear to be all-female?
Some of what the answers to this question suggest is that:
- It would be possible to make artificial sperm from another egg and then implant it into a uterus for pregnancy in the relatively near future. As a complement, this would be easier to do than a build an artificial uterus.
- Men are unnecesary because heavy work is now done by machines, with which the disappearance of men would be relatively rapid, with respect to the appearance of this technology.
- Following some feminist trends, an attempt would be made to change the sexual selection that men have had for millennia.
- This is in addition to the fact that this artificial sperm technology allows choosing how a daughter will be, without being similar to both mothers.
So, my information for start this speculation, start with a crucial fact, Once a certain technological level is reached, the attributes intrinsic to the biology of man become unnecessary, such as physical strength, which in fact begins to happen now, with which having a muscular physique is more than anything a whim (although There are still a lot of people, women who will find it attractive), but based on this, contemporary attractive attributes are more related to status, social, monetary, intellectual and different skills, than with being good at hunting or fighting.
For this even with the men dissapearing, women, will continue to be sexual beings, with the biologic instinct of the sexual contact, so we would assume lesbianism before asexuality. With this Women find other women attractive, and for the majority of the population by a specific set of characteristics, among which I believe they will persist, hallmarks of status and character.
On the contrary, athletic women show an increasing trend since the sexual revolution (of course this is because have more oportunities of not be judged by the society) and it has been noticed with social networks, again this is useless in a society with technology, but what better way to show status than with an exhibition of physical appearance that shows discipline and the economic capacity to invest and spend on health, although I believe in this case it will not be like men who seek prominent muscles, but women would only seek some muscle development, because again large muscles are unnecessary and they would be aware of it.
Then, since the Victorian Era, The trend of thinness in women began, going from the upper classes to the lower classes as an ideal ambition, with its most extreme peaks in the same Victorian Era and in the 2000's becoming unhealthy, but as consideration it seems that this was beginning to liberate women from another old role, that of producing children, because before that, women with pronounced hips with a settled belly and more prominent breasts that represented a great capacity to produce children were sought, have more childrens therefore, more pregnancies and a lower risk of death.
But at this point we need to consider that even without men, women will continue forming families with other women, but the fertilization of an egg by creating false sperm would be much easier than creating an artificial uterus, with which the pregnancy will not disappear (at least in a longer time) and I think I remember that even despite the caesarean sections, the pregnancies are complicated by certain problems in the shape of the hip (and a few other things).
Then, other interesting thing about humans is that males select females in difference with other animals, that produced an interesting feature of sexual selection that any other animal do not have the characteristic most associated with the feminine that are the protruding breasts, excessive in size for survival, larger than necessary for lactation, this is the product of the sexual selection of men throughout history. Therefore (although in an advanced society it is not so noticeable) without the presence of men and for practicality, this characteristic would be significantly reduced, since it was men who were instinctively attracted to prominent breasts.
And finally it is possible that fine features, such as smooth skin or slightly pronounced bones of the face and curved contraposition, are maintained due to technology, the heavy work would no longer be necessary and therefore the opposite of these previously masculine features would disappear.
My conclusion, is that in a completely feminine human society, as it is obvious that it happens and has happened, the character of women will change notably, becoming what is now considered masculine, but eliminating many of the historically negative characteristics of men (such as those caused by the testosterone), menawhile they keep good "feminine" characteristics", while the physical appearance would not be like that of a current woman, I think that if they were seen now, they would be almost like androgynous men than women, conserving reduced breasts, but wider hips than a man would have, but still so with a slim body and maybe even athletic.
So the question here, is actually asking for information that you have and I don't that can help me refine this thought or that maybe it shows that I am in error, or maybe it produces a completely different result.
The unnecesary easy answers could be just say "yeah, women will be just men behavior at women body" or "no, this couldnt happen, women society will be completly different free from these situations".
