A water-based lubricant is a personal lubricant whose main ingredient is water. It is safe to use with condoms and silicone products and rinses off easily, though it may need reapplying because it can absorb or evaporate during use.

A silicone-based lubricant is a long-lasting personal lubricant that does not absorb into the skin quickly and works well in water. It is condom-safe but should not be used with silicone products, as it can degrade their surface over time.

An arousal serum is a topical product applied to the genitals to support sensation and blood flow, often producing a warming or tingling effect. It is different from a personal lubricant: a serum is intended to enhance sensation, while a lubricant is intended to reduce friction.

Dyspareunia is the medical term for persistent or recurrent genital pain that occurs before, during, or after intercourse. It has many possible causes, including dryness, hormonal changes, pelvic floor tension, or medical conditions, and is worth discussing with a healthcare provider.
