Final answer:
Teenagers can avoid forming preconceptions about sex by engaging in critical thought about media messages, having open discussions with trusted adults or family members, and receiving comprehensive sex education.
Step-by-step explanation:
To avoid forming preconceptions about sex, teenagers can employ a few strategies. Firstly, questioning the messages in the media about sex is crucial. Media can often present skewed and unrealistic portrayals of sexuality, which can shape a young person's beliefs and expectations. Engaging in critical thinking regarding what is seen in movies or read online can help in discerning fact from fiction.
Secondly, discussing sex with close family members or a trusted adult is beneficial. Contrary to the myth that teens listen only to their friends, teenagers report that parents and other trusted adults greatly influence their sexual behavior. These conversations can provide accurate information and also help teens to form their own values and beliefs around sexuality.
Lastly, sex education plays a significant role. Comprehensive sex education programs, as seen in countries like Germany, contribute to lower rates of teenage pregnancy and more informed youth. Learning about sexuality from a structured and evidence-based program can diminish the development of misconceptions. Such programs should include a range of topics critical for sexual health and focus not only on abstinence but also on prevention of unwanted pregnancies and sexually transmitted infections.
