Physical causes may include: the use of controlled substances such as narcotics and alcohol; injuries to the back, enlarged prostate glands, blood supply problems, and/or nerve damage; diseases and organ disorders.

One of these sexual disorders is paraphilia. It describes a family of persistent, intense fantasies, abnormal urges, or behaviors involving sexual arousal to anything out of the ordinary. Here are some of the most common paraphilias experienced by common people:

Depending on the extent of a person's sexual preference, it is often difficult for people surrounding a paraphiliac to understand how the person behaves. They are often bombarded with feelings of contempt and anger, depending on the number of times the paraphiliac has gotten into confrontations with other. However we must always keep in mind that these people are mentally challenged and may still be salvaged. With proper psychological help and adequate support, they might get over this hurdle and lead normal lives.
