Age Dysphoria?

Sounds like a joke, doesn't it? "I feel like an 18-year-old trapped in a 60-year-old body." "No, you aren't. You're just an old pervert."

Honestly, however, it feels like it's a major part of my autistic experience. Some parts of me are still 2 years old. Many parts of me are trapped in adolescence, still trying to figure out the "adult world". And a part of me was 60 even when I was actually 5. If I could "transition" to actually be perceived as the teen/young adult that I feel like, I think I could be more comfortable -- youngsters are supposed to be as confused, and inexperienced, and clumsy as I have been all my life. 

But it still feels like a bad joke. It's probably impossible. And, in many areas, it would probably get me labeled as a predator even if my thoughts, motives, and actions are pure. So what can I do in order to unmask and be who I feel like I am *without* making the folks around me uncomfortable. No joke, just confusion.
