Before Margaret Cho launched a successful career in comedy, she taught grammar with a naughty twist.

“I was a phone sex worker, but I sounded white and I didn’t have any kind of accent so I was promoted to do recorded phone sex,” the Korean-American actress recently told Page Six. “I was teaching people English as a second language – usually Japanese businessmen – about sentence structure and syntax, but all the time was getting them off.”

“I was maybe 15 at the time,” she added. “I probably shouldn’t have been doing it, but whatever.”

Cho’s continued connection to the sex worker community has inspired her to help destigmatize the perception of the industry. The San Francisco native, 46, is also passionate about lending a stronger voice to victims of sex crimes based on her own experience as a survivor of sexual abuse.

In conjunction with a social media campaign called “12 Days of Rage,” the funny girl will debut a music video on Nov. 13 for her self-penned anthem “I Want To Kill My Rapist,” which was inspired by her own traumatic experience and aims at empowering other victims.

“I was raped from the ages of 5 to 7 by a family member and then I experienced rape — if I’m honest with my experience — I was probably raped at least 40 times,” explained Cho.

Surviving “hundreds” of molestations between the ages of 5 and 12, the LGBT activist found herself bullied for being a victim prior to her standup career. Cho explained that she found comfort on stage “because nobody could hurt me there – I had witnesses.”

She added, “On stage I was powerful and on stage was where I was able to grow up.”
