This is an 18+ idea, if you are younger please move on.
Your in a fictional world, your choice, but something is very wrong. A vast majority of women act like modern women and to add on to that they are also mostly in charge.
Not very fun, luckily you were reincarnated with the sex bit system. With it you can create and sell sex bots to help save your fellow man from these women.
Eventually, you decide when, you can even create artificial wombs for the sex bots, while cutting a deal with some ultra man haters for viable donated eggs so they can have children.
At the beginning the bots will only run on preset programs such as; housewife, best friend wife, girlfriend, prostitute, etc and eventually you will upgrade them to ai's that can grow.
You can eventually get personality matrices for your ai from women of fiction, and depending on the world your in even the normal versions of the women in your world(who act like modern women and man haters)
By the end the sex bots will basically be their own race of living women.
This idea was pretty nuts and I forgot why I thought it up halfway through lol, but just think of the drama Naruto would cause if he had a Sakura bot with a loving wife personality that bitch slaps the real horrible Sakura haha.
Have fun with it.
