Take one sheet of paper, put it straight in the fix without developing. Compare that to the border of your print. If the border is darker, the paper is fogged. If not, it's probably OK.
If fogged, you can either get fresh paper or add a whallop of KBr to the developer. The latter is not recommended in communal darkrooms...
If it ins't fogged, you have a problem. Either the film is underdeveloped - in which case going up a couple of contrast grades will help - or the scene is dull as ditchwater. That happens to me too...
In general I like negatives that are so contrasty that I have to struggle to keep them within printable range on paper.
BTW, are you developing the print enough? The easiest way to make a dull, flat print is to pull it from the developer when it looks ready. Trust me, it isn't! Find a standard time, 90 seconds is a good one, and stick to that. Never pull a print early!
