Hermophrodism

[Admin]

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

Starting as female
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.
