One of my most powerful impotence files ever, this is a re-recording of A Sissy's Greatest Sacrifice voiced by enchanting London Hypnodomme Mistress Clarissa.  This file has been updated although the script is very similar so the original description, as posted below, still stands.  Enjoy girls and prepare for the most important change of all.

Being a sissy requires making sacrifices princess. I know that you understand that. One of those sacrifices is the ability to make love as a hetero-sexual man. This idea can also be quite scary for delicate sissies so this file is designed to help you. Not only will you never be able to make love to a woman for the rest of your life after listening to this file, but you will feel a great sense of joy that this has been achieved. And as a special sissy bonus this happiness will cause you to think about downgrading other parts of your life to fit in with your true nature. You will downsize your ambition to better reflect the person you truly want to be - a maid, a secretary or perhaps a housewife. The most exciting part is that this file is permanent. Only a true sissy would want this. Do you think that might be you princess?
