My wife knows and she was the very first and only person that I have come out to. At first I don't think she was to keen on the idea because of very bad and controlling marriage to her last husband. I insured her that I was not gay and that I was not wanting have a sex change because I would make one ugly woman and I would never disgrace my family. Now she helps me to buy clothes, shoes and make up. We even share clothing with each other. She is truly my best friend and I love her so much that it can be a little sickening at times even though we are both senior citizens.
Let me add that my results is that typical and each individual must make the decision based on the knowledge of their relationship with their wife or Significant Other. Relationships and marriages have been destroyed by coming out at the wrong time or just coming out at all. I don't mean this to be negative in any way but it has and does happen.
