Stuck

A story theme in which the main character ends up ‘stuck’ in some way that forces them continue living as a female due to circumstances beyond their control. Stories of this kind might be based upon magic backfiring (wishes that were poorly phrased; magic items that malfunction or become lost, etc.) or perhaps a piece of sci-fi gadgetry that malfunctions (one memorable trope here being the idea that a body suit has to be removed within a certain timeframe or it somehow fuses with the wearer). A recurring theme (almost a ‘rule’ of T* writing) is that if a transformed character becomes pregnant then they’re stuck at least until the baby has arrived.

Elsewhere, the main character is “stuck” for more mundane reasons, such as a promise they made or a deal they entered into. That category is not usually employed to describe scenarios where blackmail or force is used to imprison the character.
