A French kiss, also known as a deep kiss or a tongue kiss, is an amorous kiss in which the participants' tongues extend to touch each other's lips or tongue. A "kiss with the tongue" stimulates the partner's lips, tongue and mouth, which are sensitive to the touch and induce physiological sexual arousal.

What is a deep kiss called?

A French kiss (also called a tongue kiss, a deep kiss, or making out) is a kiss in which one or both partners use their tongues to stimulate each other's mouths for mutual sexual pleasure.

What do hard kisses mean?

A lusty kiss on the lips (think: the classic make-out session) points to your partner being really into you—and currently aroused. Yet, a deep, heavy kiss means that they feel a relatively intimate bond with you or are looking to get closer.
