Female lubrication As with guys, when girls are turned on or sexually pleased, their vagina will release a fluid. This fluid is known as natural female lubrication and helps during sex or masturbation. In response to hormone changes, the vaginal "lips" swell, causing the fluid to cover the vaginal walls gradually. The covering of the walls makes it easier for sex or masturbation because it reduces the friction between the vaginal area and a penis or dildo.
Female ejaculation describes the ejection of fluids from the urethra or vagina during an orgasm or any time leading up to an orgasm. The fluid, which is usually described as a milky white substance, is thought to be made up of two things: urine and a clear milky fluid that resembles semen. This fluid can work as natural lubrication during sex or masturbation.
