I've noticed the same thing. I started out as more of a 1 on DebbieL's scale, but now I find myself at a 4. Once I actually attempted to understand who I was, I discovered the thrill wasn't sexual at all, but the general great feeling I get when I'm not holding part of my personality in.
Also like DebbieL said, I'd come out if it wasn't for the potential issues it might cause my wife and family. I'm ready to embrace Aleta as part of my life. Some days, I just want to wear a dress to work. Why should that be such an issue?
