OnlyFans Star Ari Kytsya just spoke to a class at Harvard about her adult entertainment career and, of course, got some backlash … and she’s ready to give haters an education.

Here’s the deal … Ari was invited to speak at the prestigious university about taboo businesses … topics she obviously is well-versed in, being a massive OF star. And yet, she still got flak from those who said her presence on campus was a joke.

Watch the clip … Ari tells us, those bent out of shape likely have zero clue what she was even invited there to speak about … and being so close-minded comes from a stigma she and some of her colleagues are hoping to change.

The adult-entertainment star says she wants to start making sexual content that is not dominated by outdated, male chauvinism … and even show that porn can have “consent” dialogue so viewers know it’s OK and normal to communicate with their partner.
