See, I was completely the opposite. When I was a kid, I was as far from submissive as you can get. I was a total tomboy, and fought like a wild thing against anyone who tried to tell me what to do. I hated being controlled and was always looking for a reason to start a fight. Even in my teen years, when I matured a bit and found my sexuality, I never thought of myself as the least bit submissive to anyone. I was always very proud of being independent and never backing down from anyone.
There was a certain ... event ... with a woman I was sort of casually seeing in college that really opened my eyes. Not that I'd been lying to myself all those years or anything, but that there was a part of me I'd never known was there. Ever since then I've been slowly learning to integrate that part of myself with the rest of who I am.
Just goes to show, you can't always judge a book by its cover.
