Here's one that is a contradiction. I think a Dom needs experience in being a Dom, before even starting. Some things just need to be experienced and can't really be taught theoretically. Not that it hurts reading up on as much as possible. Chances may be that I was just an idiot and met the wrong ladies in life, but my earliest experience of dominating women ended in me not only hurting her but also myself. Fast, hard and painful lessons in life. After those early bad experiences things got a lot better.
