This is too much, even for California.

More than 1,000 Bay-Area parents are protesting and threatening to sue their school district over a sexually explicit textbook for ninth-graders that features oral sex, bondage and sex toys – along with more garden variety guides to nutrition and general fitness.

“Your Health Today,” the 392-page guide to agony and ecstasy of the human experience, was adopted unanimously by health teachers in the Fremont Unified School District from among a handful of options, according to the San Francisco Chronicle.

It’s normally used in college level courses – not to teach 14-year-olds.

“I was shocked when I looked at the book the first time,” Asfia Ahmed, who has a son entering eighth grade, told the Chronicle.

Why would that be? Maybe because in addition to sex toys, oral sex and bondage, the book includes illustrations of sexual anatomy and detailed descriptions of sexual arousal, ranging from “excitement” to “resolution” – presumably omitting the customary dinner and movie.

There’s also – naturally – discussion of gay marriage, as well as “atypical sexual behaviors and paraphilias, or sexual mental disorders,” according to the Chronicle.

Of the latter, there seems to be plenty to go around in the Fremont School District, starting with the Board of Education.

“It talks about masturbation,” school board President Lara Calvert-York told the Chronicle. “We really want them to have a safe place to get facts about their bodies and how to handle things and how they need to be mature to deal with these things.”

At 14? Some of “these things” might be too much for 40-year-olds.

“The illustrations are extreme … Oh, my gosh!” one openly shocked woman told KPIX News Channel 5, when shown a copy of the textbook. “They are very pornographic.”

The Pacific Justice Institute, a conservative law firm, is working with Ahmed and other parents to get “Your Health Today” removed as a textbook, according to the Daily Caller. The text is “clearly inconsistent with California law,” institute president Brad Dacus said in a news release.

“No school board, regardless of their ideology, is above the law. We are hopeful that the overwhelming opposition by parents from across the political spectrum will cause the board to reverse its ill-conceived position.”

Speaking of “ill-conceived positions,” according to the Chronicle, “Your Health Today” covers them too.
