It's very common nowadays to say that most women are bisexual, or that sexuality for women is fluid.

I propose a completely scientific experiment. An island nation populated by a few select women who are to raise an entire generation of orphaned infants, all girls. Absolutely zero communication with the outside world is required for this to work. They will have no memories of men, no depictions of men in their culture, not even a mention of men in their science textbooks. From birth to adulthood, raise a generation of women to believe that only women exist, and that relationships involving two women are perfectly natural and normal. Their shows, movies, cartoons, pornography, anime, all will depict this female only world, and condition them to expect that their goal in life is to find a wife.

The question is, how many would feel that something is "not right" and refuse to engage in relationships? How many that, in normal conditions would be considered straight, would happily engage with women if they were unaware of men?
