Using the survey method, data collection was done using a questionnaire. In the end, we realized the respondents have a varied consequence of sexuality. The purpose of sexuality is multiple, including offspring, exercising in future marital life, discovering each other and having fun with the opposite sex partner. Respondents also expressed a negative opinion about pre-marital sexuality, although they were interested in any discussion of sexuality. The experience of morality and sexuality is at once disordered, commerce, sometimes a voluntary act. The nature of sexuality is to be discouraged. For some, it is imposed, while for others, it is responsible and does not prepare for married life. Similarly, the respondents stated that they were not introduced to morality and sexuality, although sexuality is considered an initiation to marriage and intimacy. High school is the most cited information channel.
