There are, to those of us who actually interview the prisoners, in fact very many reasons why people might pretend this. These vary from the opportunity to have trips out of prison through to a desire for a transfer to the female estate (to the same prison as a co-defendant) through to the idea that a parole board will perceive somebody who is female as being less dangerous through to a [false] belief that hormone treatment will actually render one less dangerous through to wanting a special or protected status within the prison system and even (in one very well evidenced case that a highly concerned Prison Governor brought particularly to my attention) a plethora of prison intelligence information suggesting that the driving force was a desire to make subsequent sexual offending very much easier, females being generally perceived as low risk in this regard. I am sure that the Governor concerned would be happy to talk about this.
