• Masochism: Can range from mild versions to extremes. In the mild renditions, activities might include bondage (being tied up for the purpose of sexual arousal), being spanked, or being overpowered by physical force. The crucial point is that they are mainly symbolic enactments done under carefully controlled conditions with a trusted partner. At the opposite end of the spectrum are genuinely painful activities such as whippings, semi-strangulation, being trampled and self-mutilation. Although sadomasochistic acts in their extreme forms can be physically and psychologically dangerous, the majority of people engaging in these behaviors do so with an understanding of the risks and stay within carefully predetermined limits.
• Pedophilia: An adult's preferred or exclusive method of sexual excitement is fantasizing or engaging in sexual activity with prepubescent children. About two thirds of the victims of pedophiles are girls, most often between the ages of 8 and 11. Pedophilia predominately occurs in males, but there have been documented cases of women who have repeated sexual contact with children. The popular stereotype of the child molester as a stranger who lurks around playgrounds with a bag of candy to lure victims is not entirely correct. It is not uncommon that the pedophile is a relative, neighbor, or acquaintance of the victim. Pedophiles commonly fall into three distinct age groups: over 50, the mid-to-late 30s, and the teens. Most are heterosexual and many are married fathers. Strictly speaking, the person who has only isolated sexual contact with children is not a pedophile and may be inappropriately expressing sexual frustration, loneliness, or personal conflict. There is no single pattern of sexual activity that fits all pedophiles.
• Bestiality: Engaging in sexual contact with animals. When the act or fantasy of sexual activity with animals is a repeatedly preferred or exclusive means of sexual gratification, it is called zoophilia. Bestiality usually involves curiosity, a desire for novelty, or a desire for sexual release when a partner is unavailable. Zoophilia sometimes involves sadistic acts that may harm the animal.

Obscene Telephone Calls
Making repeated obscene telephone calls for the purpose of sexual excitement is also considered a paraphilia. The relative safety and one-sided anonymity of the telephone provides an idealized setting for masturbatory fantasies with no worries about face-to-face contact.

There are three basic types of obscene phone calls. In the first, the caller boasts about himself and describes in detail his masturbatory act. In the second type, the caller directly threatens the victim ("I've been watching you" or "I'm going to find you"). In the third type, the caller tries to get the victim to reveal intimate details about her life. Sometimes the obscene phone caller repeatedly calls the same victim, but more often, unless the victim shows a willingness to stay on the phone and play his game, he'll move on to others.
