Are you saying that your natural, unmodified voice sounds quite female?
.... or that you have tried some modification without any instruction which has been only partially successful?
Surgery is VERY unpredictable and can be catastrophic
The most predictable/successful is a simple operation to raise the larynx (Cricothyroid Approximation, I think it's called) but all it really does is hold the larynx up, which you can learn to do yourself.
Proper voice training is the way to go - listen to the results some of the other girls have achieved.
If you're looking for "an easy fix" forget it...... good results take hard work.
- put "Transgender voice" into Google and search results to find stuff out.
