Definition - What does Lubricant mean?
Lubricant is a substance used during sexual activity to reduce friction and eliminate discomfort. Lubricant is most commonly used between two partners for vaginal or anal sex but it can also be used for solo play either alone or with sex toys.
Lubricant may also be known as lube, sex lubricant, or personal lubricant.
Kinkly explains Lubricant
There are many different types of lubricants ranging from tingly to tasty. They can be water, oil or silicone based. When using condoms, however, it's important to avoid oil-based lubricants, as they can eat away at latex, increasing the chances that a condom will break. Silicone lubricants are sometimes safe to use with latex, but it's important to check the packaging to be sure. Silicone lubricants also don't evaporate like water-based lubes do, though they can't be used on silicone-based toys. There are even lubricants that double as massage oil for foreplay.
Research some lubricants online or at your local adult store before buying, and always be sure to read your labels and pick what's best for you.
