MJ, I gather you're quite a lot younger than me (I'm 54), but I've also just started ("woke up" after a 30-yr+ denial phase), so I'll chime in. I've come out to my wife of 31 years, and she's having difficulty with it (predictable), so I'm being patient and taking baby steps and letting her get used to the idea. Today I just bought my first female clothing - a pair of jeans and a top. I already had some panties. I've also begun to let my hair grow, although it hasn't gotten noticably longer yet, and nobody has noticed. I have 3 kids, 18, 24 and 26 all still living at home, so I have to go slow. But I'm learning. I have a support group nearby that meets twice a month, and a good friend, so I have places I can cross-dress in safety. These are small things, but let me feel like I am progressing. I also have asked my family doctor for a referral to a gender identity clinic for assessment. That's slow, though - it's been a month with no call-back. So I'm also looking for a gender psychologist - haven't found one yet, but I'm looking.
Welcome to the family, and I hope I can help, at least a little.
