It happened on a Wednesday. First, information was gently inserted into everyone’s mind, information about what would soon occur.

Going forward, people between approximately the ages of eighteen and twenty-five would undergo a sort of second puberty: they would develop into fully functional hermaphrodites. The majority of people will have this hermaphrodation occur between twenty-one and twenty-three, with only about five percent having it occur before twenty.

For males, this would take the form of developing breasts, loss of chest hair above the bottom of the rib cage, a slight widening of the pelvis and the growth of a second reproductive system, a female one. This process generally takes six months, though breast development may continue sporadically well into one’s late twenties.

For females, the main physical changes would be mainly limited to simply developing their male reproductive system, with few or no other visible changes. Development of the male reproductive system generally takes only three to four months for females.

These, however, are only the most common outcomes, and the tail of possibilities is long. For instance, it is entirely possible, for example, for a male to end up with an entirely feminine appearance by the end of this second major sexual development period. Or the opposite for someone born female, or anything in between. A person’s desires can have an influence on this, for example, a closeted trans woman is more likely to end up with a feminine appearance. These outliers may take a year or more to fully change into their new appearance. Though the majority of people do follow the rules above.

The last thing that changes is sexual preferences, those attracted to men gain an interest in breasts on men. Everyone gains new urges and reflexes related to their new parts and mostly gains an interest in the parts they were formally uninterested in. These are again generalisations, other outcomes are possible, rarely some may find their orientation changing, some may become bi, others may go from straight to gay, or the opposite, such cases would be rare.

Everyone ends up with a dual libido, that is, it is possible to be aroused with only one’s male parts, or only one’s female parts. In fact, at some point, their body will “lock in” to one or the other, releasing a pheromone signal that will cause their partner to “lock in” to the opposite. Once someone …
