Comparably, soldiers get high stress because of their life style. Their life is full of tension and obeyness. They have to obey their higher's order also they have restrictions in their life. Furthermore, mostly they are young and full with passion. But the passion is restricted by rules. Sometimes the soldier's passion appears in outlaw ways as sexual violation and sexual infamies. Therefore, to understand this situation, we researched the beginning of 20's men and soldier's consciousness of sex. These are the result for this research. Privates and recruits' attitudes of sex are little different. First of all, privates have more openness about sex than recruits but there is almost no difference. Second, they have similar result about sexual desire and drive, but the research shows privates don't have more sexual desire than recruits. Third, the methods to solve the sexual desire are exercise and internet game of ignorance. Forth, in the standard of sexual infamies, recruits thought as a sexual infamies even though it's a tiny situation. Also recruits highly thought about the possibility for sexual accident than privates. Fifth, most of soldiers said the education about sex in the army is not useful for them and they feel that they need professional council for solving their problems. This research provides the understandness about consciousness and behavior and to show the direction of sex education in the army. Even though the soldiers said they don't feel sexual desire, there are many sexual problems. Therefore, the Korean Army, by providing rightful interpretation and education of sexuality, must help the soldiers freed from sexual problems.
