Erotic massage may be used in sex therapy as a means of stimulating the libido or increasing the ability of a person to respond positively to sensual stimulus. In some cases, erotic massage can be a form of foreplay without sexual gratification, intended to heighten the sensitivity of an individual prior to another engagement where sexual arousal and fulfillment is intended. In other cases, erotic massage may be used professionally to help men address issues of premature ejaculation.
