Your healthiest option is to consult with an endocrinologist. They will perform baseline bloodwork. After the results they will prescribe a regimen for you. Dosages will vary depending on the doctors thought process. They will most likely prescribe low levels to allow your body to acclimate and see how you respond. They may then increase or even lower your dose.
Hormones are powerful chemical agents that perform their work on the cellular level. Frequent testing is required to ensure deadly medical conditions are detected early.
Your sexual performance and libido will also diminish to s point you can't perform. Hormones will usually be the point at which the spouse will want out of the relationship. You are moving light speed. Transition is not a race, but a marathon that takes years. You may want to start exploring going out as a woman. Interact with the world. Transition is serious work. The pitfalls are many and if you lack the mental strength to endure them. Booom. Huge explosion.
The questions you ask are absolutely better asked in the TS sub forum. Just don't expect a chorus of "You go Girl" answers.
I just read your last 2 previous posts. I don't believe you do understand the consequences of HRT nor what dosages would be appropriate. If going out as female could get your wife fired. Where do you think you might transition? You do need to understand this. Transition is a very public process. Events tend to get real very fast. Nobody transitions in stealth after living decades as a male!!
