Over the past few decades, several related changes have contributed to increasing the prevalence of premarital sexual relations in Nigeria. Demographic transformations such as rising age at marriage and increasing levels of urban migration are playing a part in changing the nature of male-female relationships.

In particular, the paper explores conflicts between contemporary sexual identities and traditional models of gender and family as these tensions unfold in premarital sexual and reproductive decision making.
