Introduction: Sexual intimacy in any long-term relationship is very important for the relationship to last (Armstrong, 2006). Married and cohabiting couples need to be comfortable together to be sexually intimate. Sexual intimacy is defined as being sexually intimate with your partner at a level where both individuals are aware of what their partner likes sexually and what they expect (Armstrong, 2006).

The following literature helps support the hypothesis that sexual intimacy is important for heterosexual couples who have been married or involved in a cohabiting relationship for more than two years.
