Dan Olson is a man with a profound depth of knowledge. I have never met a man that knows more about the BDSM / Kink scene than Dan. He spent the bulk of the semester discussing the virtues of rectal beads and progressive pegging and discussed the erotic nuances of Nabokov's "lolita". He even provided us with graphic (however unsolicited) masturbation demonstrations. Unfortunately it was a visual arts class and I failed all my exams.
Great Visual Arts teacher he has knowledge about what he teaches, he cares about the students and even if he is a little arrogant he's still super nice and you learn TONS from him.
