title: [Sexual behaviour and use of condoms by adolescents in our environment].
abstract: OBJECTIVE
  To identify sexual behaviour in adolescents.
  
  
  METHODS
  Transversal, descriptive study, by means of an anonymous structured questionnaire.
  
  
  METHODS
  Urban secondary school.
  
  
  METHODS
  Simple random sample of 84 students (4th year of ESO--c. 15/16 years old).
  
  
  METHODS
  Personal details, sexual practices, use of condoms.
  
  
  RESULTS
  61.9% were girls. Average age was 16.4 (95% CI, 16.2-16.6). They had a girl/boy-friend or casual partner (33.7%) and stable partner (60.7%). 82.2% had total or sufficient trust. Boys' first masturbation was between 14 and 16 (46.8%). 100% had done so by the age of 16. 72.3% of girls had never masturbated at this age (P<.001).Boys' first kiss on the lips occurred between 14 and 16 (46.8%); 100% had done so by 16. 60.7% of girls had done so between 14 and 16, and 92.2% by 16.30.1% of boys had had their first experience of coitus by the age of the questionnaire, whereas 22.5% of girls had. Both sexes used a condom on 71.4% of occasions.38.1% had sex with penetration, 46.2% masturbated. 22.2% had had 2 sexual partners, 8.9% had had 3, and 40.0% had had 4 or more. Condoms were used in 83.3% of relationships with penetration.
  
  
  CONCLUSIONS
  This is a sexually active population, susceptible to sexually transmitted diseases (STD) and unwanted pregnancies, as it does not use condoms in every relationship involving penetration. Health education activities need to be encouraged.
