The assailant needs to be held accountable for their actions. Reporting the sexual assault may be one way you choose to turn your anger into a positive action. Reporting may be the only way for the assailant to get treatment. Victims may experience a variety of sexual concerns after an assault. They may want no sexual contact whatsoever, they may need intimacy - stroking, nurturing, holding and not want to be sexual, or they may experiencing some confusion about separating sex from sexual abuse.
Sexual healing takes time.
It's OK to ask your partner to nurture you and not ask you to be sexual at this time. A patient, gentle, intimate partner is helpful in your healing process. To retreat sexually is a normal coping mechanism. You have a right to refuse to be sexual until you feel ready. Rape is not sex.
