Historically, school principals are known to have lost their jobs over it. School board members do not like to deal with it either because many have also lost an election over it. Superintendents do not touch it with a ten foot pole. And even though people think they are sexually liberated and enlightened, dealing with the topic of sex is still taboo. The mere mention of the topic stirs broad emotional response.
People seem to take extreme positions with few in the middle.
Responsible and reasonable people who would never think to call the school are quick to call when sex is mentioned. Many parents do not want the school to deal with teen sex, pregnancy prevention, termination, or its consequences. And yet, parents themselves do not feel comfortable to discuss sex with their children. Society seems to have relegated sex education to the distortions of televisions, cheap movies, sleazy magazines, and locker rooms. Ironically, the best sex education program is one which teens get with an unwanted pregnancy.
