Hello Jaime,
I am glad you have decided to address the profound issues that confront you, but after I read your post a couple times, it sounds like, "I just figured out I was transgender so I guess I'll sign up for SRS." I would politely suggest that you really need to think this through, and not make unilateral decisions that will enormously affect not only your life, but the lives of your wife and your son.
As Denise mentioned, SRS is usually the last step in a long, often painful, and always expensive path. Virtually all insurance companies, and most surgeons in the US adhere to WPATH guidelines for SRS, namely living a year full-time as the gender you identify with. Have you considered what that would involve, both personally and professionally?
Seeing a gender therapist is a wise first step. Your second step should be talking to your wife. Your marriage belongs to both of you, and she deserves to know what is going on. Lack of trust, and feelings of betrayal are often just as much or more lethal to a marriage than the actual transition.
With kindness,
Terri
