Define Dating??
Having casual....Dinner or Drinks? Is that dating or just meeting with a friend?
Having casual....S** while out? Is that dating or just meeting with a friend?
If the above is not dating. Then, nope never dated more than one person.
Seriously! I find it very difficult to be with more than one person. If someone else has gotten my attention to that magnitude, then it's time to move on from the present.
