The fact is  slave, most Masters are far more concerned about your attitude and your training than with how you look or what your current circumstances are.
Get good training first, and then the right Master might choose to customize your body to suit His preferences, or He might keep you just the way you are.
The important thing is that at that point it will be His choice, not yours, so you don’t even have to think about it at all. Right now all you need to focus on is training.
