Why do females get wet before sex?

The female sex response is a natural reaction of the body in preparation for and during sexual activity. One physical response common to this process is vaginal lubrication produced when excited. This lubrication serves both emotional and functional purposes. First, the fluid can serve as a natural lubricant to reduce potential tissue injury during intercourse by decreasing vaginal friction to ease penetration during intercourse for increased comfort and pleasure. On the emotional side, vaginal lubrication during anticipation or actual foreplay enhances arousal and promotes pleasure by increasing genital awareness as it heightens sensations during sexual interactions.
