@Oldmonk,
Wait a minute .... you don't know?
You REALLY don't know what all this means?
Where have you been the last 15 years? Head down , playing video games? In prison or Monestery? Sheltered childhood? On the austistic spectrum?
I think you need to get out into the world. Talk to and interact with lots of people so you learn how to 'read' body language and facial gestures.
THEN and only then should you even consider dating.
