Human Biology and Alien ecology don't mix.

Your father had been imprisoned. Your paperwork put you under the guardianship of his chief advisor Alice Drake, apparently females had much more legal leeway even in wartime on this planet. A kind woman that knew the laws of this planet inside and out, as well as a good grasp of its culture. She was going to do anything to keep you safe whether you liked it or not.

What she didnt know was how the food, the atmosphere, the pollen, the very air gravity and light would effect a developing human body!

You were not happy when subtle signs began to show as you grew up on this alien world. A normal healthy childhood within the embassy walls, education and entertainment even a gym but the environment wreaked havoc on your very genetic make up...

You didnt grow into the strapping young man your father was in his youth. Body hair refused to sprout, muscles became stubborn to develop, your skin softened, hips swelled. Despite everything you tried your body seemed determined to make you ever more feminine! Luckily breasts had not developed, your body toned and definef from years of attempting to fight this trend, but alas your near hourglass figure and facial features made it impossible to convince anyone you were male! That is without taking off your pants. The people at the embassy knew but they were under strict instructions not to speak of your condition.

The human doctors were not much of a help either. They couldn't stop this transformation any more than you could. Masculinity was out of your reach. To compound the issue there was THAT other thing.
