Fabian Nicieza is also on record as being a big ole Dick Grayson fanboy. (I remember him also once saying that he thought Dick and Tim were the two most capable people in the DCU.) Though his fan-boying does tend more towards the male crush version, like in having Tim look up to him and think he seems too cool for school.
But he did also have those ninja people of Ra's ask the butt question. He definitely knows the guy's hot.:-) But I don't know if he ever much deals with his sexuality in an internal, detailed way. Where as Devin Grayson's obviously really interested in the way Dick relates to people, including sexually.
