Seek both theraputical and medical guidance first!
You need to be involved with a therapist who specializes in transgender issues. This was something I did before starting HRT, jointly in fact with my wife. Transitioning is a serious step and not something to be entered into blindly. A transgender therapist can help provide you with all the pertinent info you will need as well as providing a professional analysis as to whether or not this is a viable option for you. If so, they can also recommend medical guidance and supervision to ensure that you are transitioning safely.
Hope this helps you out some with this issue.
Love,
