One has to gain the insight that these sense contacts have no intrinsic value in themselves. That's all that's happening. As long as one reacts to these contacts as if they had importance, there is sensuality. Where there is sensuality, there is also irritation, the two go hand in hand. Sensuality is satisfied when the sense contact impingement was pleasant.
Irritation arises when the sense contact was unpleasant.
It doesn't have to issue as anger, shouting, fury, hate or even resistance. It goes together with being a sensuous human being. It is necessary to realize that the reaction is our own, so that we may start work on ourselves. It's occurring constantly, without let-up, so that we have innumerable occasions to become aware of our inner world. Becoming aware doesn't mean yet that we can get rid of our reactions.
