The sexual education guarantees the well-being, the sexual health and the genre equity. For it, the present investigation proposes to analyze the perception of the adolescent males and women on the Integral Sexual education in Lima-Peru. There was selected a random sample of 569 students (38.08 % males and 61.92 % women) between 10 to 20 years. The results showed that 83.63 % feels confidence to speak about sexuality, being the women those who have major faith than the males. 26.61 % prefers to speak about sexuality with its friends, 17.89 % with the teachers and in less percentage with the parents and brothers. The interrogated persons admit that to speak about the topic there's important the good teacher attitude, the safety and if the school develops the subject-matter. But the motives for which they don't speak about sexuality it is for the shame, the fear of the mockery or because the school does not offer the suitable ambience.
