Pornhub seems like the last place on earth you’d find a 50-minute, fully clothed calc lesson, but this Taiwanese teacher is the tube site’s newest star

In the depths of Pornhub, buried beneath a mountain of hardcore erotica, a 34-year-old Taiwanese man named Changhsu (張旭) taps away at a green chalkboard while speaking a steady stream of Mandarin. In nearly all of his 226 videos, he wears a gray hoodie and black-rimmed glasses, and he never once does anything even remotely pornographic — no blow jobs, no 69s, no anal. He’s on Pornhub for a different reason: To teach calculus.

Changhsu has a master’s degree in mathematics, and he’s been teaching online and in Taiwanese cram schools — which provide supplementary learning classes for determined students — for 15 years. He lectures on YouTube, and in 2020, he developed an online course with its own dedicated URL. If his 520 positive Facebook reviews are to be believed, he’s a fantastic educator — most of them are some variation of, “Nice teacher!”

Last year, Changhsu saw an opportunity to spread his numeric gospel on Pornhub. “Since very few people teach math on adult video platforms, and since there are so many people who watch videos on them, I thought that if I uploaded my videos there, a lot of people would see them,” he tells me (Changhsu asked us to edit his English for clarity, because it’s not his first language). It’s true that non-pornographic videos like “I Deliver You a Pizza and Don’t Put My Weiner in It” or “Minecraft Tips and Tricks 3: Fast and Free House” aren’t uncommon on Pornhub, but Changhsu appears to be the only math teacher on the website (unless “Jerking off to CALCULUS” counts).
