Breitbart's Dr. Susan Berry is reporting on the poster discovered in a classroom at Hocker Grove Middle School in the Shawnee Mission School District in Kansas. One of the students was so shocked by it that she took a photo of it and showed it to her parents.

They were outraged, and for good reason.

The poster, entitled "How Do People Express Their Sexual Feelings" lists actions such as oral sex, grinding and masturbation.

“Why would you put it in front of 13 year-old students?” asked the girl's father, Mark Ellis.

When he attempted to get an answer to this question from school authorities, he was even more concerned to learn that this vile poster is considered to be "teaching material".  What is his daughter being taught in this school?

“It upsets me,” he said. “And again, it goes back to who approved this? You know this had to pass through enough hands that someone should have said, ‘Wait a minute, these are 13-year-old kids, we do not need to be this in-depth with this sexual education type of program.’”

School district spokeswoman, Leigh Anne Neal, told Fox News that the poster is part of a larger curriculum which she claimed was "abstinence-based".

“The poster that you reference is actually part of our middle school health and science materials, and so it is a part of our district approved curriculum,” Neal said. “However the item is meant to be part of a lesson, and so certainly as a standalone poster without the context of a teacher led discussion, I could see that there might be some cause for concern.”

Neal claims the curriculum is similar to other programs being used throughout the country.

“The curriculum it is a part of, it aligns with national standards around those topics, and it’s part of our curriculum in the school district,” she said.

Dr. Berry discovered that the curriculum, known as “Making A Difference,” is published by selectmedia.org and recommended by the U.S. Department of Health & Human Services (HHS) as a “pregnancy prevention intervention.”

The publisher's website claims the program is designed to help teens modify their behaviors to reduce the risk of pregnancy and HIV and STD infection by emphasizing abstinence as the only way to eliminate these risks.

Module 2 of the program, which is called “Understanding Adolescent Sexuality and Abstinence,” offers “an overview of reproductive anatomy, discusses messages about sex, discusses how people express themselves sexually [apparently reinforced by the poster], and the benefits of abstinence,” Dr. Berry reports.

Regardless of its intent, Ellis thinks the curriculum is inappropriate for middle-school aged children.

“This has nothing to do with abstinence or sexual reproduction . . . " he said. “I would like to see that this particular portion of the curriculum is removed from the school.”

If it isn't removed, he will remove his daughter from the sex ed classes at Hocker Grove.
