Answer to Question 1
There are a variety of reasons for having sex the first time. Some of these include interpersonal and structural reasons.
Interpersonal Reasons: The majority of first sexual relationships are with a romantic partner. A person may feel obligated to have sex for fear of hurting the other's feelings or losing his or her interest. Others experience physical arousal and follow their impulses or are simply curious about sex.
Structural Factors: Teenagers are more likely to engage in sex at an early age if they experience family turbulence, such as parental conflict before or during a divorce, remarriage, or re-divorce; if they live with single parents who are sexually active; or in neighborhoods where adults who are role models don't have steady jobs and bear children out of wedlock. In such situations, adolescents may disengage from their parents, looking to peers for emotional support, and thereby hasten their entry into sexual activity.
