Purpose: The purpose of this study was to analyze the history of exposure to obscene material, and examine sexual attitudes and intercourse experience in order to develop an effective program for university students. Method: The data were collected in May, 2012 from 385 students attending 3 universities in Korea. An independent t-test and ANOVA were used to determine the differences with regard to sexual attitudes and intercourse experience according to general characteristics and history of exposure to obscene material. Results: Sexual attitudes significantly differed according to timing of first exposure to obscene material (p<.001). Intercourse experience was significantly different according to timing of first exposure to obscene material (p=.016) and type of exposure to obscene material (p=.032). There was a negative correlation between first exposure to obscene material and sexual attitudes (p<.001), and a positive correlation between first exposure to obscene material and intercourse experience (p=.017). Conclusion: Results of this study indicate that history of exposure to obscene material should be considered as an important variable in managing the sexual health of university students.
