This may be one reason consensually performed BDSM activity has the potential to increase relationship intimacy between the involved partners (Sagarin, Cutler, Cutler, Lawler-Sagarin, & Matuszewich, 2009).
It seems many of the women who have participated in studies on BDSM are single, which makes relationships the status of importance when studying BDSM practices (Pascoal, Cardoso, & Henriques, 2015; Weinberg, 2006).
One example of what may be defined as kinky sex is sexual role play, which may comprise activities such as dressing up as a nurse or a school teacher.
But the definition may also include activity connected to dominance and submission as in BDSM (bondage-discipline, dominance-submission, sadism, masochism).
BDSM practitioners often become aware of their fantasies and feelings in the latter half of their teens (Bezreh, Weinberg, & Edgar, 2012; Weinberg, 2006).
