I have moved you post to the voice section of the forum where you will find a wealth of information on producing a feminine voice. I have had a good deal of experience with trained voices and am willing to work with others who would like to attempt this approach. For now, just post your questions in this thread. A surgical voice still requires a knowledge of a trained voice so I recommend attempting a trained voice first as surgery isn't always required. Unfortunately, I was one of the people who required surgery to produce a feminine voice but without knowing how to use a trained voice, my voice would still sound masculine.
To produce a trained voice, you need to tighten up the muscles between your larynx and your jaw. If you start out saying EEEEEEEEEE with your normal voice and tighten the muscles, your voice will rise and at some point break. A feminine voice is produced by keeping your pitch above the break point. Then it becomes a matter of inflection (the constantly changing pitch) of a feminine voice.
Don't force your voice and if you feel any discomfort, stop what you are doing and ask for help. Pain is a sign that continued usage will cause damage to your voice. Over the short term, you voice will recover but long term damage could require surgery to correct.
If you feel you need it, I will do Skype sessions as it can be a little difficult getting it right at first.
