I like my hole stretched, so thick is a preference over long.
Not that I've ever refused a dick, regardless of dimensions.
I've refused GUYS because of attitude, how stoned out of their gourds they were, how unclean, etc. But never have I ever refused a dick based on size or dimensions.
And I've played with quite small to quite large, and all combinations in between.
But my d'ruthers is leaning to thicker, for the stretch.
