A quick and perhaps superficial search leads me to the determination that opinion is about evenly divided as to whether "intelligence" or "power" is the ultimate aphrodisiac. I didn't see much mention of "looks" at all as a contender for the top position. And "money" would seem to be a subset of "power", so is not really in the running.
I would contend that to achieve and maintain "power" in today's world, where physical force is secondary, it is necessary to have and utilize "intelligence".
My conclusion is that "intelligence" is the ultimate aphrodisiac. And it also might prove quite useful for those whose aim may be something other than finding the ultimate aphrodisiac, at least towards the carnal.
