Inconsistent or insufficient parental nurturing as a child inflicts a sense of parental betrayal. The child soon learns that intimacy brings pain and learns to withdraw emotionally. Sex, to these individuals, ushers in a sense of security and eventually leads to addiction.
Some of the other causes of sex addiction are -
Early sexualization or early initiation to sex by sights, sounds or touch(es)
Childhood abuse is a key contributor to adult sex addiction. Research reveals that as a child 71% of sex addicts have been physically abused, 83% have been sexually abused, 97% have been emotionally. Some children are less impacted by abuse primarily due to their inherent personality and also due to adequate adult support.
Stress causes some people to use sex as a mode of escape.
There are reports of a propensity for people with other forms of addiction such as alcoholism, gambling or drugs to gradually become addicted to sex as well.
Sexual Addiction can sometimes be due to other Psychiatric Disorders such as Obsessive-compulsive disorder (OCD), Narcissistic personality disorder, and Bipolar disoder.
In some cases, neurological disorders such as epilepsy, head injury and dementia can lead to sex addiction
Sexual addiction can be a result of biochemical imbalance in the brain.
Some drugs such as apomorphine and dopamine are found to lead to hyper sexuality.
