Mutual masturbation refers to the act of engaging in sexual activities with a partner but without actual intercourse. Some synonyms for this term include manual sex, hand sex, manual stimulation, and digital sex. Other terms that may be used to describe this sexual activity include self-pleasuring in front of a partner, or simply watching each other masturbate. This sexual activity continues to gain popularity as couples explore new ways to enhance their intimacy. Despite being perceived as taboo in some cultures, mutual masturbation is a safe and pleasurable alternative to traditional intercourse, particularly for couples who are not ready to engage in full sexual activity.
