Foreplay

In human sexual behavior, foreplay is a set of intimate psychological and physical acts between two or more people meant to increase sexual arousal.Foreplay involves different acts such as kissing, touching, embracing, talking, and teasing (teasing, in this case, may include methods of satisfaction, such as erotic sexual denial).[1] Sexual stimulation of all kinds, such as manual or oral stimulation of erogenous zones are considered foreplay. Sexual role playing, fetish activities, and BDSM can also be considered foreplay, though they may also accompany intercourse and not just precede it. Of the various forms of foreplay, the most common include fellatio and cunnilingus.

Psychologically, foreplay lowers inhibitions and increases the emotional comfort of the partners. Physically, it stimulates the process that produces an erection in men, allowing them to penetrate an orifice. In women, it helps stimulate the process that leads to erection of the clitoris, raising of the cervix (elongation of the vaginal canal), and the production of vaginal lubrication, allowing penetration to take place comfortably.
