Overseas exploration teams and colonizing armies might have been male-staffed, but they'd only have been considered the advance teams for the women who came in and organized the new societies in places like America. It's a society where the development of an idea is more important than its initial creation. Patent and copyright laws would give less priority to the concept of something, more priority to its application. It was a society where home and family were more important, a society with fewer opportunities for misfits and conconformists to make their own alternate social rules. As in our society here and now, home consumption is the driving economic force.
Industry exists to make things for people, particularly things for women and families.
Girls and boys would still grow up facing rigid gender roles to which to conform, but those roles would be different in ways big and small. The differences would lead from the way that girls would also be expected to organize everything, while boys would be discouraged from getting in the way of the ladies and to go off and play sports and not think too hard about trying to become doctors or presidents. Because The Family Structure would be even more important in a feminine-led society, sex mores would, alas, be little more liberated than they are in our world. A man who gave a woman lots of great orgasms would be a prized possession. Adultery for the sake of romance, however, would be strictly punished if caught, particularly if it led to a pregnancy outside of an arranged marriage.
