Gasoline and skin - how dangerous?

I was at the gas station today filling up the little 2-gallon plastic container so I could refill my lawn mower’s tank.

I looked up (at a passing fire engine) and the nozzle of the pump came partially out of the container – and sprayed on my arm and my left leg. I didn’t have any means of wiping off the gas, so I drove home (about 3 minutes) and then got a wet towel and washed off my left arm and both legs.

Now (6 hours later) I see no damage to the skin. Did the exposure do anything serious?
