If I were to cane, say, you, I’d try to look stern while I was doing it. Of course, I’d also be very turned on, and very happy with your submission and trust for my judgment.
My experience is that a lot of submissives don’t enjoy that microsecond when the cane actually lands on their bare and presented bottom or thighs. But a few seconds later they like the pain and the warmth. A few minutes later, they like the spreading warmth and delicious soreness. Later still, they love the feeling that they’re in a relationship where being caned for misbehaviour is part of life. Because they have someone in charge of them who cares about their behaviour and welfare.
