Kinky sex refers to any sexual acts that are generally considered to be unconventional. In other words, kinky sex fall outside the realm of what's considered vanilla sex, or what is regarded as conventional sexual behavior.
Although the popular definition of kinky sex suggests that it involves bizarre and unusual acts, it is increasingly being portrayed as a sense of sexual playfulness, rather than perversion. What is considered kinky varies widely between individuals, but may include BDSM, role playing, sex toys, exhibitionism, fetishism, and more.
Not all kink is necessarily kinky sex. While there is always a sexual element, intercourse is not necessarily required. For example, a dominatrix will generally not have sex with her slave, but the power exchange is clearly kinky.
