Either hard or long cranking can cause gasoline to get into your oil, causing the smell. Or you can have blow-by where the piston are not sealing on the cylinder wall. Gasoline in oil is not a good sign. It dilutes oil, stripping it of its lubrication and protection properties. Get your oil and filter changed ASAP.

When that happened to me I had a lower o-ring on an injector leaking.Changed the oil every other day till I fixed it.Neighbor thought I was nutz.Then I read here that after the engine is warmed up the gasoline evaporates out.Wouldn't rev it at all till completely up to temp.
