ISD is often an intimacy issue. Common relationship factors that can reduce sexual desire include: conflicts; toxic communication; controlling attitudes; contempt or criticism; defensiveness; breach of trust (infidelity); lack of emotional connection and spending too little time together. People who are most at risk of developing ISD have experienced trauma (incest, rape, or sexual abuse), or were taught negative attitudes about sex by their family (or by their religion) while growing up. There are other medical and psychological factors too.
