Yes, your lips actually have the greatest number of nerve (sensory) receptors followed by your hands. Conversely, areas such as your back are not nearly as sensitive to sensory stimulation.
The hands, lips, tongue and genitals have the largest sensory representations. The hands, lips and mouth area also have the largest motor area representation. For more information on this, use the keywords "sensory and motor homunculi"
The brain is where nerves are most concentrated
You mean why is it "possible" to taste spicy food despite absence of its "taste receptors" in the tongue. Well, its because spicy food contains capsaicin. It is an organic molecule found in chillis and peppers capable to producing a burning feeling upon tissue contact. This is due to it binding to a neuronal receptor VR1, allowing movement of ions and such would result in a burning sensory sensation. That is why "spicyness" can be felt even on your lips when eating spicy food.
Some clams appear to have blue lips but in reality, they don't. The lips appear to be blue due to the reflection of their lips in the water.

Lips play a crucial role in shaping sounds during speech production. They can control airflow and vibration to produce different sounds and help with articulation. Additionally, the movement of the lips can also affect the resonance of the voice, influencing the tone and quality of speech.

Touch sensory receptors in your lips begin sending signals to your brain that they are touching soft tissue. This will lead to "happiness hormones" being dispersed, making you feel good and comfortable. Also lots of bacteria and other microorganisms are transferred between the two.
The map of the sensory cortex reveal about the density of touch receptor a larger area of the cortex is devoted to analysis of cutaneous sensations arising from hands, lips and tongue than other areas. The motor cortex is located on the post central gyrus.
Tactile corpuscle are the nerve endings in the skin that respond to the lightest touch. They are most concentrated on the fingertips and lips.
The baroreceptors, located in the carotid sinuses, respond to changes and absolute levels of blood pressure. These nerves go to centers in the brain stem and trigger changes in heart rate and venous tone.

LipsĀ are a visible body part at the mouth of many animals, including humans.Lips are soft, movable, and serve as the opening for food intake and in the articulation of sound and speech. Human lips are a tactile sensory organ, and can be anĀ erogenous zoneĀ when used inĀ kissingĀ and other acts ofĀ intimacy.
