'The Stranger' is a masturbation technique which the user commences by sitting on their hands until they go numb and as a result cannot feel through their hands when they masturbate.

To jack yourself off after letting your hand go numb: see example below

Step 1: Find a hard surface such as a a Wood Bench or Marble Floor
Step 2: Sit on your Dominant hand, palm down for 5-7 minutes until 88% of feeling or more is lost in that hand
Step 3: Close your eyes, manifesting a pleasurable scenario, then proceed to gratify yourself with your hand in its current numb state

Result: Out of body experience simulating/fantasizing another person administrating hand and or oral* stimulation on yourself.

*Jergens can be used in conjunction with the stranger for simulated oral relief
