The sample contained 203 participants, 101 males and 102 females, the age from 18-24, from Serbian language speaking area (Serbia, Montenegro, Republic Srpska). As an instrument of the research we used “Sexual Behaviour” questionnaire specially constructed for a National study of Serbian sexual behaviour. For our research we used questions about sexual behaviour divided in 5 parts: foreplay, coital behaviour, masturbation, sexual fantasy, sexual dreams, which we were statistically compared with 9 factors of sexual attitudes detached by factorial analyses.
Our findings showed that males have had significantly more coital experience than females (p<0,001), earlier beginning of coital activity (17,32±2,25yrs. vs. 19,78±2,73yrs, p<0,001), more sexual partners in general (5,4±7,6 vs. 1,7±1,5, p<0,001), more sexual partners in last month (1,7±1,7 vs. 0,7±0,7, p<0,001) more frequently masturbation (p<0,01), more dreams and fantasies about coital interactions, then females (p<0,001). But, males has less liberal sexual attitudes than females (p<0,001).
On the basis of received data, we concluded that sexual behaviour is in agreement with biological influences on genders and their social roles. We think that our findings showed hesitancy in adolescents to admit to having sexual experiences in context of social undesirable premarital sex. Regarding to contradiction of sexual attitudes and beginning of sexual activity we conclude that sexual attitudes are relatively changeable category then sexual behaviour, which is relatively stabile category.
