Enacts new GS 14-27.8A to provide that a person who initially consents to vaginal intercourse is not deemed to have consented to any penetration occurring after the person withdraws consent during the course of that vaginal intercourse. Allows a person to withdraw consent to engage in vaginal intercourse in the middle of the intercourse, even if the actual penetration is accomplished with consent and even if there is only one act of vaginal intercourse. Requires the withdrawal of consent to be clearly communicated in a way that a reasonable person would understand to constitute withdrawal of consent. Provides that a defendant who continues the act of vaginal intercourse after consent is withdrawn is deemed to have committed the act of vaginal intercourse by force and against the will of the other person. Applies to offenses committed on or after December 1, 2017.
