The first thing I'd do, is go for a sail on a significantly bigger boat. It could be as part of a class, a charter, or just as a guest for a daysail. You want to figure out if you don't really like *sailing,* or just don't care for *dinghy sailing.* Take some time to compare what you learned on the little boat and see how it scales up to the big boat. Then decide.
I'm going to go against the conventional wisdom on this site - which says to sail dinghies, then medium boats, then bigger boats - and agree with Minne's advice. If you don't like sailing dinghies, don't sail dinghies. If you enjoy sailing bigger boats, sail bigger boats. Your learning curve will be different, maybe slower with respect to learning what each individual control of the shape of the sail does to the boat's speed and balance in varying wind conditions. You might have to do more book and classroom learning to make up for what you might learn in the dinghy, but you can still get to a respectable level of sailing competence if you want to. Of course, you'll miss the spontaneous dunkings that come with learning on a dink.
