But she said it was very "wrong" to feel the rape was in any way her fault.
"My rape had nothing to do with my choices. Drug dealers don't rape people any more than a family man does. The rehab counselors didn't correct that belief. My own mother didn't correct it. F*** anyone who meant well but told me to look at this 'as a sign' that I needed help.
"It is likely that my daughter will one day be sexually assaulted. I can't prevent that. She can't prevent that. But no matter what the circumstances, it won't be her fault."
She has two children - Rafella, aged seven, and Memphis, aged five - with estranged husband Michael Mosberg.
When a follower said she was brave, she said she didn't feel it.
"Who said I was being brave, Sarah?" Kirke replied. "I don't think anyone is trying to be self-congratulatory here, Sarah. Being 'brave' really isn't the point. For me, it's an effort to be supportive and to lead the younger generation by example in hopes that they won't accept rape as anything but a crime against them."
Before she made the statement she had sent out a note of support for Dr Ford, the DailyMail reports.
On Thursday the Senate Judiciary Committee was sorting through the allegations Kavanaugh had sexually assaulted Dr Ford when they were both teenagers in the early 1980s.
Ford told the committee she is "100 percent" certain it was Kavanaugh who attacked her at a party in 1982. She also said she believed he was going to rape her.
"I'm hugely grateful to this woman today," she noted.
She noted that she understood why women don't always report their sexual assaults.
In the past week Padma Lakshmi, Busy Philipps both revealed they had been raped at a young age. They wanted to make a point that women who are raped are often afraid to report it.
