I recognise the character you are drawn to is directly from the book..

However since we do live in a POP culture society, what if you pointed him to the Tom Cruise role in "Interview" as I recall, there werent any overt bisexual overtones, unless biting Louie counts. (Plus we know, Tom is worried about how he is imagined, right?) If this is the case, Ole Drac biting any number of guys..Harker, Renfield, the whole ship worth of crew.. would make him rather , well, gay, right?

And while I know its not the same era as with Claudia, The Lestat protrayed in later film "Queen of the Damned" has no overtones,Does he?

Maybe a trip to Blockbuster and a few "see, I told you" comments might start to chenge his mind
