Planned Parenthood is under fire after a new undercover investigation found staff members promoting bondage, whipping and other violent sexual practices to minors as young as 15.

Lila Rose, president and founder of Live Action, which conducted the investigations, warned that Planned Parenthood's sex advice "glorifies kids acting out rape scenarios."

"It's extremely dangerous counseling: they're undermining and invalidating the crucially important rule of no means no," Rose said in a July 15 statement.

Live Action released two videos July 15 as part of an undercover investigation series called "SexEd," which looks into Planned Parenthood's support of violent sexual activities for minors, specifically in clinics that receive federal funding for sexual education programming.

The latest videos were released just days after the announcement of a lawsuit against a Colorado Planned Parenthood affiliate charging that it failed to report the sexual abuse of a 13-year-old girl.

The new footage shows Planned Parenthood workers from two clinics in the Denver area offering sex advice to undercover investigators, whom they believed to be underage patients coming for counseling. The staff members explained kink, bondage, gagging, asphyxiation, whipping, being "tied up," sadism and masochism, and a range of other explicit sexual actions to the patients.

"So, it's just like playing with the different power dynamics in the bedroom," one worker said about bondage to a self-described 15-year-old girl during the undercover investigation.

One worker encouraged her teenage patient to search the internet, go to sex shops, and watch porn to discover new fetishes and "role playing" ideas. She acknowledged that these avenues might lead to computer viruses and discovery by parents, but suggested that the teen do her "research" on her phone to avoid parental oversight.

Both clinic workers also referenced the explicit sadomasochist book "50 Shades of Grey." The staff member from the Lakewood Health Center said that while she found the book "anti-feminine" and "male-controlling," and refused to read more than a few pages of it, it could be an "eye opening" resource for her self-described 16-year-old client.

"I might recommend that the two of you read it together, just to see if it's something that the two of you would be willing to do," she told the teenager.

Both clinic workers also advocated for the use of a "safe word" during sexual activity. One Planned Parenthood staff member explained that the word "stop" "can kind of get mixed up when you're having intercourse."

"Does she really mean 'stop,' or does she mean, you know, whatever," she said.

The clinic workers were both supportive of experimentation, suggesting that there is no intrinsically "wrong" violent or dangerous sexual activities in which the teens could participate.

Sex, and specifically kink, is "more of a combination between pleasure and pain," said one. "It's kind of whatever you guys want to try or are willing to experiment with."

Any sexual action, including choking, biting and whipping, the other said, was safe and normal so long as the teens had "open communication" with one another.

In releasing the undercover videos, Rose noted that the federal government gives more than $70 million per year for "sex counseling."

"Here's an abortion corporation, which gets 45 percent of its budget from the taxpayers, telling 15- and 16-year-olds not only to have sex, but also to choke each other in the process. Police should be busting down its door," she said.

Rose called on parents to speak up for the safety and protection of their children.

She referenced a case earlier this year in which a 16-year-old girl was charged with murder after police said she strangled her boyfriend to death during sex. The girl allegedly told investigators that they were involved in a "consensual sex act involving strangulation."

"Parents need to get on the phone right now," Rose said, "and ask their principals and superintendents, 'Do you have a relationship with Planned Parenthood? Are you okay with this sort of behavior being pushed on my children?'"

"This won't stop until people take action locally for their kids."
