How do you perform auto-erotic asphyxiation?

The Best, Safest, and of course the divine way of performing the Auto Erotic Asphyxia is through doing "Pranayam" an age old Indian breath controlling method . stopping breath without any outer support you just have to inhale and stop the breath inside for few second and than release. with practice you will be able the hold the breath for longer duration with all the health benefits and pleasure of asphyxia. And yes it is safe and divine too...
