The instrument used to elicit information from the respondents was a well-structured questionnaire. Result from the study shows that it is important to impact knowledge about sex and sexuality to adolescents. As, many of the respondents show positive attitude towards sex education (65%), they knew its effectiveness (54%) and consequence of risk behaviors (86%) but lacked appropriate knowledge (42%).
