At the origin of males, males were just shatted chunks off the baby factory to wreck the enemy and bring back calories through a slit in the hull for a reward of repetitive production. So at the start, women were bigger than men, because that's how asexual procreation evolved to sexual procreation.

You men are just angry female acid pee, like bomadier beetles can spray. Your one job since you can't make babies, is to be immune system activities outside the body. That's why you were made inside a female and you don't have a baby factory in you. Your are immune system that escaped the female body.
