In general, the release of this fluid serves you sexually by making vaginal and vulval play more comfortable. And, in particular, it probably evolved to make easier both penile-vaginal insertion and the movement of sperm up the vaginal canal, increasing the likelihood of impregnation. Women sometimes lubricate vaginally when they are not sexually aroused, and women often feel erotically aroused without becoming vaginally wet. Excess lubrication, even though some women feel almost embarrassed by it, can easily be solved by use of an absorbent external panty-liner.
