The system of having mostly 2 destrinct sexes is resulting in a lot of societal tension and unhappyness, people are bitter due to being confined by the sex they were born into, some people try to medically change their sex but even then you will never be able to escape the reproductive role. Instead today medical transition will make you infertile if you take it too far and you end up having to rely on freezed sperm/eggs.

So what if we could modify humanity so people will both be able to get pregnant and impregnate?

With genetic engineering it would be possible to turn humans into hermaphrodites.

Self impregnation
Why have someone else impregnate you (that have different genes) if you can impregnate yourself?

This means that there would be evolutionary pressure towards avoiding having someone else impregnate you unless you get something else in return. One potential solution is have mutual impregnation but then there would be a big incentive to cheat and not be impregnated yourself.

This would slow down evolution drastically since there would be less DNA shuffling

Preventing self impregnation via a genetic lock
It's unclear how to actually do this in practise but one option is to make sure eggs can only be fertilized by sperm that are genetically different from the sperm produced by the one being impregnated.

The advantage of using a genetic lock is that it eliminated the need for government to police these things, depending o implementation it could also make reproduction via incest difficult to impossible.

Hermophrodite sex
Sex with non-hermoprodites would be possible. Hermoprodites will have XZ chromosomes, their sperm will carry Z chromosome, their eggs will carry X chromosome. This if a hermoprodite impregnate a non-hermoprodite the offspring will be a hermoprodite (XZ), if a hermoprodite is impregnated by a non-hermoprodite the result will usually be male or female (XY or XX).

The picture above is from an intersex female, actual hermoprodite genitals would be a bit different.

Should we keep the scrotum?
The reason why testies are not confined safely inside the body is in order to keep an ideal temperature for sperm production, is this really necessary? Maybe we could find a better design (genetic engineering).

One potential option is to instead put the testies inside the labia majora.

Rape and forced marriages
An evolutionary incentive for rape would remain since you can only get get pregnant once a year while you can impregnate other people on a weekly/daily basis, in addition you will no longer be able to get pregnant once you become too old (typically 40 to 50) and after that impregnating others will be your only option. We might see old people forcefully impregnating the young (abusing their power).

We could also see people using other means to be able to impregnate others such as by being better looking, having more status, providing resources, etc.

Pregnancy and breast growth
Currently a lot of breast growth will occur at puberty. Pregnancy will add some more size (at least temporarily).

https://pubmed.ncbi.nlm.nih.gov/24100511/

But do we really need people to grow breasts prior to impregnation? one option is to instead have breast growth only after impregnation resulting in people being more like current males if they are not impregnated or given estradiol.

One advantage of having everyone be like current females plus penis and the ability to impregnate is that it would make people more equal reducing social tensions. Otherwise we would not really get away from the current system where we have pretty much 2 different social classes based on sex.

Physical abilities
Even today with technology male strength is still useful to a significant extent. We do not however need separate sexes for that. There are multiple solutions for this

0. Allowing people to naturally build significant muscle strength from weightlifting
1. Natural genetic variation resulting in some people naturally being stronger/taller.
2. Anabolic Androgenic Steroids

The Androphilia problem
A general issue with trying to eliminate males is that current females are to a very large extent androphilic which create a demand for males that do not really have any good purpose besides sexually satisfying these females.

This makes it harder for Hermprodites to impregnate XX females since most of them would probably prefer XY males over hermoprodites. Hermoprodites might end up having to resort to rape to make XX females pregnant to a significant extent.

Transsexualism
It's very likely that many hermaphrodites would like to change their physical appearance of gender presentation. This however would not have the same potential benefits as current MtF transsexualism since people would already have largely female bodies.

We might see some people modify themselves medically to become more like the old XY males. Breasts lost most of their utility value once you as a female have had all the children you wanted and have finished breastfeeding.

The "Natural FtM" option
If everyone start female with no ability to make sperm then self-impregnation would not be possible (or very difficult). People would only be female when they are young and attractive. Over time your clit would grow until it become a penis, no external testicles would ever develop.

Start of female fertility: 9 ± 4
Clit start growing: 23
somewhat functional clit/penis: 27
end of female fertility: 30
fully functional penis: 33
start of male fertility: 35

One potential issue with this is that if for some reason all people over 5 would die than that may doom humanity since by the time someone can finally make sperm there would be no females left. This is resolved by not having a fixed time where people start become male, we could have 2 types of humans

Type A
Start of female puberty: 9 ± 4
Clit start growing: 15
somewhat functional clit/penis: 17
End of female fertility: 19
Functional penis: 20
start of male fertility: 22

Then there could be a drug to delay or completely halt the male puberty allowing for forced breeding or sex for pleasure.

Type B
Start of female puberty: 9 ± 4
clit start growing: 30
somewhat functional penis: 35
end of female fertility: 40
fully functional penis: 43
start of male fertility: 45

Reproductive sex distribution
Given type A and B we get the following

Infertile: 25%
sperm production: 55%
female fertility: 20%

Neurology
Being successful would now pay off greatly in terms of reproduction since most people would be able to impregnate a lot of females eventually when successful. Thus there would be a strong evolutionary pressure towards risk-taking.

Even when subjected to estrogen and low testosterone (female state) most people would still display masculine behaviour traits. People would start out like males trapped in female bodies.

It is worth noting that even today a lot of females are highly willing to take big risk for little/no potential payoff in terms of survival and reproduction, this is likely a bi-product of male evolution where the same trait evolved in both sexes when it was only really beneficial in one.
