Adolescence is the period in which a person is mature, forms their sexual roles and attitudes in the perception of sexuality, and sexual behavior at that time becomes part of a normal person's development. Given the sensitivity and insufficient exploration of this area, there is a need to understand the sexual behavior of young people, their way of thinking and to determine the knowledge young people have about sexual health. Aim: To examine and compare the attitudes of parents and adolescents about early involvement in sexual intercourse. Respondents and Procedures: A cross-sectional research was carried out in Medical higt school in the period from then until 2018. The survey included 75 students of 3-5 grades of the mentioned school and 75 parents. The research was conducted using a cross-sectional study. The survey used the method of interviewing to get an insight into the attitudes of the respondents about early stage sexual intercourse. Results: Women in relation to male parents considerably agree with the claim that sexual intercourse has been premature (p<0.001) before the age of 17; parents aged 45 to 54 do not statistically significantly disagree with the need to provide counseling centers and preventive programs for adolescents (p <0.001). There is a statistically significant correlation between the feelings of living the faith in the parent in relation to the attitude towards sexual intercourse before the 17th birthday (p = 0.007). Students consider significantly less important to encourage open parenting on gender issues than pupils (p = 0.037), and considerably agree with the claim that it is okay to have a sexual intercourse for just one night (p = 0.036). There was a significant correlation between the feelings of religious life in the student in relation to the attitude about the risk of sexual intercourse (p = 0.018), the attitude about the necessity of sexual intercourse in order to maintain the partner (p = 0.013) and the attitude about the early impact of early sexual intercourse and frequent change of partner to reproductive health (p = 0.020). Conclusion: Parents in relation to adolescents have a significantly more negative attitude towards sexual intercourse 17 years ago, according to gender only one night, and significantly more emphasize the damaging impact of early on in sexual relations and the frequent change of partners to reproductive health. They also emphasize the need to educate young people about sexually transmitted diseases.
