A sexual enhancement product that alters nerve activity in the penis to prevent premature ejaculation. Many prolonging sprays have numbing agents such as benzocaine and lidocaine, which limit sensation; however, some use menthol, peppermint oil, and other substances to distract the user without actually causing a numbing effect.

Men typically wear condoms after applying these prolonging sprays in order to prevent the active ingredients from affecting their partners. Most prolonging sprays are completely safe for everyday use.
