Since 1996, the Teenage Diaries series has given tape recorders to young people around the country. They conduct interviews, keep audio journals, and record the sounds of daily life — usually collecting more than 30 hours of raw tape over the course of a year, edited into documentaries airing on NPR’s All Things Considered. Whether it’s the story of Amanda, a gay teen trying to understand her sexuality, or the story of Juan, who crossed the Rio Grande with his family illegally, these stories offer insight into the mysterious life of teenagers.
Primary sex characteristics are those directly related to the sex organs . In males, the first stages of puberty involve growth of the testes and scrotum, followed by growth of the penis.  At the time that the penis develops, the seminal vesicles , the prostate , and the bulbourethral gland also enlarge and develop. The first ejaculation of seminal fluid generally occurs about one year after the beginning of accelerated penis growth, although this is often determined culturally rather than biologically, since for many boys first ejaculation occurs as a result of masturbation.  Boys are generally fertile before they have an adult appearance.
