I totally agree IB.
And thanks to everyone who have responded.
I decided to ask this question after a discussion with a friend. My personal opinion is that anal doesn't make you less dominant, it's a service that you require or an intimacy with another you desire. It isn't the act itself. As IB said, it is the dynamic and openess that counts.
I think it definately seems like a hard concept to discuss - and I don't know whether its because, like Em mentioned, dominants who enjoy are in the minority (as well as the submissives who will serve such a request) - or whether it is more the inability to be open about it.
