BACKGROUND Sexual Orientation is an enduring pattern of romantic or sexual attraction, with the attractions broadly incorporated under heterosexuality and non-heterosexuality. Societal and other factors seem to affect individuals' perception of their self-identified orientation. Thus, this study sets out to document the distribution of sexual orientation, level of self-reported satisfaction, and factors associated with sexual orientation among unmarried university students. METHODS A cross-sectional study involving 550 respondents sampled using a multi-stage sampling technique. Data collected via a self-administered questionnaire and analyzed via IBM SPSS version 20.0. RESULTS Most respondents (93.6%) were heterosexuals, 4.7% bisexuals, 1.3% lesbian women and 0.40% gay men. More heterosexuals (80.4%) were fully satisfied with their self-identified sexual orientation compared to 57.2% of non-heterosexuals. Respondents who had religious upbringing and those whose parents were currently married were less likely to have sexual orientation outside of heterosexuality. CONCLUSIONS The most prevalent sexual orientation was heterosexuality, with more heterosexuals also expressing satisfaction than others. With the level of dissatisfaction expressed by those who are not heterosexuals as well as the factors associated with heterosexuality, it is plausible to conclude that societal values and/or prejudices constitute major factors in individuals self-identifying with some particular sexual orientation and the satisfaction derived therein.
