Final answer:
The statement is true as many adolescent romances do not include sexual intercourse. Adolescents value input from parents/adults about sexual behavior and largely aim for monogamous relationships in the future, influenced by sex education and societal attitudes.
Step-by-step explanation:
The statement that many adolescent romances do not include sexual intercourse is true. During adolescence, young people experience increased awareness of sexuality and often begin their first romantic relationships. However, these relationships do not always involve sexual activity. Late adolescence might see a shift towards more significant romantic relationships over peer relationships. Contrary to some adult fears, data suggests that teens listen to their parents or other adults when it comes to sexual behavior more than just their peers.
Additionally, while teens may hold progressive views on topics such as non-marital childbirth, it does not indicate an abandonment of traditional sexual values like monogamy. The vast majority still express the desire for a mutually exclusive partner in the near future. Furthermore, sexual attitudes in youth can be shaped by factors such as the level and type of sex education received, which varies greatly across different regions.
