Hmm... well, I didn't start dating until I was almost 18 (I'm 24 now), but let's see...

Dated M for a few months,
single about 2 months
Dated A for a few months,
single about 6 months
Dated J for almost a year
single for about 4 months
Dated a LOT of people, but none serious for about two years
Dated N for 8 months
Did on/off thing with N for another 6 months
Single for about 6 months
met, dated, and became engaged to the final Mr. Ginger!

So thats... about a year and a half single out of 6 years... not counting the two year casual dating stretch.
