Good sexual health is a part of overall physical, mental and social well-being. If people are unaware of sexual health needs (information about risks, vulnerability, access to good sexual health care etc.) , they may get deprived of the knowledge needed to make crucial choices about their own body and hence, the future.
Young people are one of the most vulnerable group of this deprivation who face barriers to sexual health information, especially in developing countries. In order to fill this void, sex education is the preventive tool and main point of focus, especially in children aged 10-19 years.
The goal of sexual health information/ sex education is to inculcate the knowledge in young individuals for the best possible integration between physical, mental and social aspects of personality. 
Sex- It is the biological characteristic that differentiate a person as female or male. 
Sexual health- It is a state of physical, mental and social well-being in relation to sexuality and not merely the absence of disease, dysfunction or infirmity (WHO). To maintain sexual health, there must be a constructive, effective and deferential approach to sexuality and relations.
Sexuality- It is an aspect of human life that is expressed in thoughts, behaviors, desires, attitudes, practices, values and roles. It encircles sex, gender, sexual orientation, pleasure, intimacy and reproduction.
Sexual rights- Sexual health can be achieved only if some rights are respected and protected.
As per WHO (updated 2010), sexual health rights, recognized internationally, include:
consent of the intending spouses, and to equality in and at the dissolution of marriage.
Sex education- Sex education is defined as a program that aims to build a strong foundation for lifelong sexual health by acquiring information and attitudes, beliefs and values that affect interpersonal relationships. [4,5]

For young people
This education must begin before puberty and must include information regarding:
Health and education professionals including teachers, nurses, medical practitioners, social workers and others are important components in providing sexual health education. These professionals should have appropriate sex-based information to impart it to clients in a non- judgmental and non-discriminative way. Counselling should help individuals to receive adequate information about their bodies, health and available options. It should include contraception (methods and effectiveness, complications and side-effects), mother to child transmission of HIV, testing for HIV, protections against STIs and other concerns related to sexual health.
In India, TARSHI (Talking About Reproductive and Sexual Health Issues) NGO has been counselling people by providing accurate information about sexual and reproductive health through telephone helpline.
