My DG came to me in my very first "actual" LD (fully lucid). I didn't know he was my DG at the time, but I've seen him more than once since. I don't know if this is normal, but for me, it seemed as though I had known him for a very long time, and I instantly trusted him. He literally guides me in my dreams when I need him most. I also just have this sixth sense that tells me its him now... as every time I see him, he looks different (except that hes always older than me, and always has a crazy hairdo). My DG actually taught me all my dream control techniques, and he will make me more lucid at times when I'm not. Hope this helps!
