Foreplay 调情
（重定向自Contrectation）
In human sexual behavior, foreplay is a set of emotionally and physically intimate acts between two or more people meant to create sexual arousal and desire for sexual activity. Either or any of the sexual partners may indicate sexual interest to initiate foreplay, and the initiator may not be the active partner during the sexual activity. Foreplay stimulates both partners' sexuality, lowers inhibitions and increases emotional intimacy between partners, and implies a certain level of confidence and trust between the partners. In animal sexual behavior, the loose equivalent is sometimes termed 'precoital activity'.
