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'.

"Foreplay/Long Time" is a song written by Tom Scholz and first performed by the rock band Boston on the band's eponymous debut album, and as their second single, on Epic Records in 1976. It combines an instrumental introduction, "Foreplay", to the main song "Long Time", generally played as one on the radio and listed as one track on the album. "Long Time" peaked at No. 22 on the Billboard Hot 100 the week ending March 5, 1977. The standalone "Foreplay" was released as the B-side of Boston's next single "Peace of Mind", which was released in April.
