Ingredients designed to numb sensitive tissues. The most common use for lubricants with numbing agents is to delay ejaculation and to extend sexual pleasure. Numbing agents are also known as analgesics or anesthetics, and the most popular agents are benzocaine and lidocaine.

Both of these substances are safe in small amounts. However, you should exercise extreme care when using lubricants with numbing agents, particularly when having penetrative anal or oral sex. The numbing ingredients can decrease your sensitivity to pain, increasing the chances of accidental injury.
