It can be considered that some traditional values have been lost in contemporary society. However, many authors claim that in the context of love relationships, traditional gender roles are still very much intact. Gender dynamics in romantic relationships refer to relationships between men and women and how gender roles and expectations are portrayed in those relationships. This paper deals with the research of gender dynamics in romantic relationships, with the special aim of examining the differences in sexual attitudes, behaviors and emotional communication between men and women. The research was conducted in August 2024. A survey (questionnaire as the instrument) was used as a research method, and the sample included heterosexual people in a relationship, marriage or cohabitation between the ages of 20 and 34. The results of the research showed that for women, emotional closeness is very important before entering into sexual relations with someone, but also when "losing their virginity" and that they would not be able to enter into sexual relations with a person they are not in love with or in a relationship with. Men and women did not show significant differences in the importance of the partner's physical attractiveness, both groups stated that the physical appearance of the partner was important to them. Young people were asked about the use of contraception in the relationship, specifically who is responsible for using contraception, in case they have sexual relations with their partner. The results showed that women claim that both they and their partner worry about contraception, while men say that they explicitly worry about contraception in their relationship.
