Turn on? You mean you want to approach them with a view to a relationship? If so, live by their rules for a while, be a saint, a perfectionist etc. Their rigid rules will hopefully relax some once you've got to know each other and then you can start showing them your inner renegade. This is all in the assumption that your rigid, orderly man wants a risk-taking partner to compliment them but doesn't know it. If that's not the case then a) I'll eat my hat, and b) find someone more suited.
