Sexuality is the one of the most important parts of human life. The aim of our study was to identify the factors influencing the onset and age of sexual initiation in students and drawing attention to the need to improve access to sexual education in Polish schools at a sufficiently high level. An original questionnaire with 31 questions was used for the study. Data were collected using the Google Forms tool. A total of 7528 students participated in the study and 5824 underwent sexual initiation. The mean age at sexual initiation was 18.1 years. Logistic regression analysis was performed to show factors influencing the onset of sexual activity, while linear regression analysis was used for factors influencing the age of sexual initiation. Religion, drug use, smoking, alcohol consumption, type of housing, and conversations with parents about contraception or sex affect the onset of sexual activity. The age of sexual initiation is affected by religion, the age of the first viewing of pornography, quality of life, the size of the city of residence, smoking and drug use.
