In all the various ways we seek to label our sexual preferences, to share with others what it is that turns us on, here we have it: Sapiosexual, the closest orientation I feel that defines me. I used to identify as a bibliophile, but I moved past that.
There are many many forms of intelligence: cultural, emotional, structural, historical… Any type of deep seated inner wisdom can be an intellectual prowess that I find irresistible. It is inline with being a Gemini. The dual sides, the double extremes: yes, I do want both depth and surface.
Also, sapiosexuality, for me, transcends hetero/homo sexuality. I flutter like a moth around those lightbulb type beings. A brain sparkling from kinetic energy and the light of insight shining from behind their eyes. I can own that a strong physical attraction matters a lot to me in regards to who I choose to spend my time with. But there is a prime differentiator that I have a hard time explaining.
The intellect that turns me on is one that can not be denied. It is the difference between attempting to prove superiority by wit and a person who just oozes knowledge as a way of being. Beyond contrived conveyance, it is simply how the person moves through their world with trust, with accuracy, with understanding, and with curiosity.
