I rather think you may be pruning all the stems which will produce flowers Betty. The more you prune, the more shoots will grow but you need to give them a chance to do their business.
Once it has flowered, then just prune back those stems which have flowered. Cutting the whole thing back every year isn't giving it chance to do very much I'm afraid.
They can be rather ungainly shrubs but once you have got it to flower, you can then see how to shape it in future
