This study was conducted to investigate the factors that influence sexual intercourse experience of university students in Korea.

We selected 244 students who completed a questionnaire about general characteristics, sexual attitude, sexual intercourse experience, depression. It was analyzed by logistic regression using sexual attitude of university student, father, and mother as explanatory variables.

The results showed that sexual intercourse experience was more frequent in the respondents who were more open about sexual attitude, those whose mothers have more open mind to sexual attitude, and those who were less depressed.

The sexual intercourse experience is important to affect the upcoming adult period in university students. This study suggests that it is necessary to develop systematically the sexual education program in university and society.
