I don't think you're an oddball at all - I can relate quite a lot. I certainly didn't have any words planned out, and every session we'll hit a wall where I go non verbal and if Im lucky I can just about nod or shake my head.

I did not in any way 'plan' to disclose. It just happened quite naturally. Obviously I had been very consciously holding back and not saying anything (also because its too confusing and I can't describe it right), and I think one day my T just asked a question where I could be honest, or I could not respond, and i just decided in the instant to go for it. I didn't say much - just gave one word answers (where I had words), and gave facial expressions to express what i didn't have words for.

If you have a good connection with your T, then you will disclose when you want to, and when it is the right time for you. You don't need to rely on finding the words - I would expect your T will help you with that
