ABSTRACT
There has been an unprecedented transformation and revolution in human culture in the 21st century which cut across all sphere including sexual values. This transformation has also been noticed in consensual unions over the last few decades in many developed countries in the West most especially among students in the university (Blom et al 1993, Bumpass et al 1991, Kiernan 1996). This has given birth to a culture of cohabitation, and there is a growing trend of cohabitation and premarital sexual intercourse since the 1960s (Scherrer & Klepacki 2004; Musick 2007). The changing trends in the social life of Nigerian of recent have made many practices like cohabiting in higher institutions in shared hostels an accepted norm. Several studies which looked at the impact of cohabitation of unmarried couples have been conducted and there is uniformity in their result which shows higher risk of marital disruption, disruption in education pursuit, unstable family background ( Bumpass & Sweet,1989), and lower commitment to the institution of marriage (Bennett et al. 1988). Also, various degree of association has been found between premarital cohabitation and divorce in Europe (Svarer, 2004, Liefbroer & Dourleijn, 2006) and USA (Phillips & Sweeney 2005, Teachman, 2002, Kamp, Dush, Cohan, & Amato 2003).
