Dr John Collee expresses this view bluntly -'accept teenage sex as a reality and learn to live with it'. However this implies there is nothing wrong with it.
Teenage sex is certainly wide-spread and has become the norm by later adolescence.
One in five girls and one in four boys are sexually active before they are 16. By 24 more than half have already had two or more sexual partners. A combination of biological and social factors exerts enormous pressure on adolescents to start having sex early. In boys, testicular enlargement is the first sign of puberty. This starts at about 12 and is normally finished by the age of 14.
