Sexual partners are people who engage in sexual activity together. The sexual partners may be in a committed relationship, either on an exclusive basis or not, or engage in the sexual activity on a casual basis. They may be on intimate terms (in which case they are often referred to as "lovers") or anonymous, as in the case of sex with a stranger, a one-night stand, or a prostitute. A person can be another person's sexual partner even if the sexual activity is illegal, socially taboo, or otherwise in breach of a trust or commitment. A person may have only one or more than one sexual partner at any one time, either as polyamory, polygamy or in contravention of convention.
As such, the term sexual partner can be applied to both consenting and non-consenting sexual relationships.
