The Multiple Orgasm Trigger (TM)
An approach that can separate orgasm from ejaculation in men (and women), enabling multiple orgasms. Is this yoga? No. It is mildly degenerative (like female multiple orgasms) and only reaches to the throat center, where-as yoga is regenerative and goes ecstatically to the third eye, and beyond. Even so, this is a step in the right direction, especially for men.

Twelve Step Recovery Programs -- 12 Step Cyber Café
Yoga purifies the nervous system, usually resulting in a reduced need for artificial intoxicants such as alcohol, tobacco and drugs. However, if substance use is excessive, yoga may not be enough to clean the inner windows of perception, and additional measures may be necessary. The twelve step program developed by Alcoholics Anonymous in the 1930s, and since expanded to address many other forms of addiction and obsessive negative habits (including sexual), is a proven program that is available to anyone worldwide. The 12 Step Cyber Café is a good place to start. There are many resources here.
