The research used survey design with a target population of 6085 students from public secondary schools. Based on Yamane's formula, the sample size of 375 students was selected by simple random sampling to participate in the study. Data were collected from this sample using standardized questionnaires; the Family Assessment Device (FAD) and the Adolescent Clinical Sexual Behavior Inventory (ACSBI-S). Data were analyzed using descriptive analysis, Analysis of Variance (ANOVA), Independent t-Test and Correlation analysis. The findings indicated that there was statistically significant positive correlation between family cohesion and teenagers’ sexual behavior. Family cohesion had a positive correlation with sexual knowledge at r=.200; p-value= .000. Therefore an increase in family cohesion has a corresponding positive influence on the student sexual knowledge. Family cohesion on the other hand had a positive and significant correlation with sexual interests (r=0.135; p= 0.11). The findings imply that family cohesion could be used in regulating some of the sexual behavior domains of teenagers.en-USFamily CohesionSexual behaviorSexual InterestArticle
