Lubricants provide immediate relief from dryness and are usually applied before sexual activity. They reduce friction and enhance comfort. There are three main types: water-based, silicone-based, and oil-based. Each type has its own set of advantages and considerations. For example, water-based lubricants are easy to clean but may need frequent reapplication, while silicone-based lubricants last longer but can be more challenging to wash off.
