Many reports examine relationship length and quite often infer that length is really a proxy for closeness within the relationship. Generally speaking, as intimate relationships boost in duration, condom usage decreases (Civic 1999; Crosby et al. 2000; Ku et al. 1994; Manning et al. 2009). Furthermore, this pattern tends to duplicate it self in subsequent relationships. Ku et al. ’s (1994) sawtooth theory defines this noticed pattern by which teenage boys utilize condoms in early stages in intimate relationships, then utilize diminishes with relationship length, which in turn increases once more from the beginning of a subsequent relationship. Other work has found a bad relationship exists between length and regularly making use of contraception ( ag e.g., Aalsma et al. 2006; Brady et al. 2009; Fortenberry et al. 2002; Ku et al. 1994; Manlove et al. 2005). Likewise, Kusunoki and Upchurch (2010) report reduced quantities of condom usage than hormone techniques with greater relationship timeframe. While longer extent can be related to decreases in condom usage, a far more comprehensive way of adult relationships requires focus on relationship characteristics and characteristics aside from length.
While building on these scholarly studies, we focus attention in the subjective aspects of relationships. A couple of studies discover that closeness that is emotional greater relationship quality among subgroups of young adults and teenagers are both connected with reduced condom and contraceptive usage ( ag e.g., Aalsma et al. 2006; Brady et al. 2009; Gutierrez et al. 2000; Inazu 1987; Katz et al. 2000; Manning et al. 2009; Pleck, Sonenstein, and Swain 1988; Santelli et al. 1996).
