"If the sex is bad, leave": South Korea wakes up to its sexual revolution

“Why do you need to be engaged or feel some deep responsibility to have sex?” she wrote. “If they’re hotties with bodies just hop on.”

“Who cares about goddamn attachment,” Lin wrote in another post, adding an expletive-filled sentence that expressed her hatred of men who underperform in bed. “From now on, I’ll try them out and if the sex is bad, I’m never gonna meet them again.”

Lin is part of a grassroots sexual revolution sweeping South Korea, where a deeply conservative society is beginning to loosen up when it comes to sex, and women are challenging centuries of strict gender roles in relationships.
