Foreplay refers to any form of sexual activity that occurs before the main act of intercourse. It can include kissing, touching, caressing or other forms of physical intimacy that help to arouse and stimulate both partners physically and emotionally. Foreplay is an important part of a healthy and satisfying sex life as it helps to build anticipation, desire and sexual tension between two people before they engage in intercourse. It can also increase the likelihood of achieving orgasm during sexual activity by heightening arousal levels and increasing sensitivity.
