Lips are a visible body part at the mouth of humans and many animals. Lips are soft, protruding, movable, and serve as the opening for food intake, as an erogenous organ used in kissing and other acts of intimacy, as a tactile sensory organ, and in the articulation of speech. The skin of the lip is very thin compared to the rest of the face. Because of this, the blood vessels appear through the skin of the lips, which leads to their notable red coloring. The lip also lacks sweat glands or sebaceous glands. Therefore, it does not have the usual protection layer of sweat and body oils that keep the skin smooth, inhibit pathogens, and regulate warmth. For these reasons, the lips dry out faster and become chapped more easily.
Lips are our communication centers. It's how we speak and make ourselves heard. The phrase ''read my lips'' is an expression of how we use our lips to be understood by others. Without lips, most communication would be impossible. Lips are also an erogenous zone because of their high amounts of nerve endings. The lips therefore play a crucial role in kissing and other acts of intimacy. As the mouth, lips, and tongue are among a woman's most erogenous zones, stimulating a woman's mouth and lips during acts of intimacy has been shown to elicit pleasure and to have a direct stimulatory effect on arousing her genital organs. Reproductive psychologists have suggested that one reason the female lips are seen as sexually attractive might be because they mimic the appearance and sexual swelling of the labia of the vulva, and that a woman's lips are effectively a secondary sexual organ. This is consistent with research showing male sexual attitudes towards a woman's lips and mouth to be very similar to those towards a woman's vulva. Furthermore, in many cultures of the world, a woman's mouth and lips are veiled because of their representative association with the vulva, and because of their role as a woman's secondary sexual organ.
Lips tattoos are a symbol for feminine sensuality and sexuality. Almost all lip tattoos are representation of female lips. Lip tattoos are associated with love, sex and the feminine mystique.
