A major source of sexual learning is sex education classes in school (Levy 1992). In the absence of effective sex education, the immature adolescent must make major decisions without adequate knowledge (Bjorklund 1998). This descriptive survey correlation method of research was undertaken to come up with findings on attitude towards sex of Villaba National High School students. It was also its purpose that this study may be instrumental in the proper guidance of the said students particularly in the area of adolescent sexuality. Simple frequency counts were used to determine their Attitude towards the various aspects of sexual relationships and average scores determined their Attitude towards the ten aspects of sexual relationships. Z-test was used to test the null hypothesis which states that, "there is no significant difference between the attitudes of boys and girls on the ten aspects of sexual relationships," at the significance level of 0.05. This research finally concluded that there are differences between the attitudes of boys and girls towards the various aspects of sexual relationships particularly on courtship, petting, pre-marital sex, and trial marriage or live-in. Z-test established a significant difference between the attitudes of boys and girls on the ten aspects of sexual relationships.
