I think you are not aware of the biological reality of the sexes and why we evolved as we did. We have male and female sexes because somewhere long long long time ago we had a "split" to share roles in raising offspring, not just in humans but in animals also. One sex (male) to gather resources and other sex (female) to take care of for the offspring. That's not some "alien" construct designed to enslave us or make us unhappy but a biological and evolutional necessity.
