I was recently searching for an old Fictionmania story. If I remember it correctly, it involved a US Military Lieutennant and 4 or 5 of his men being captured in the Middle East, whereupon they are each given water that transforms them. They awake as women and are told they will now have to accept this as their fate. They are put through numerous humiliating acts to reinforce the idea that they are girls, the final test being, "If you can say the following three times without interruption, you can regain your male form: 'I am a man, I have always been a man and have no desire to be a woman" (or something along those lines).
Anyway, due to certain "stimulations" they receive while trying to recite the lines, they fail and ultimately have to accept their new roles in life.

Anyone out there remember the name? I searched for hours thinking of every possible way to pull this one, but no luck. Any help will be appreciated! Thanks!
