Where to start

I have been going to do this for years.  I'm just afraid that I can't stay anonymous. I'm not out to very many people.  Only people on the down low themselves, and some gay men I think I can trust.  My wife.  She has told a few people in her family.  No one in my family really knows.  They may suspect, but don't know. I am going to put my thoughts together, and hopefully will share them and hopefully along the way help someone.  I hope to write later.
