Goddess Belle likes to train her new males with the pain/reward principal. She will hurt them very badly, typically with her whip and get them to the point of being sprawled on the floor begging for mercy. Then she will reward her male by letting him adore her feet. This way over time his brain gets rewired to enjoy the pain for her because he learns that will lead to a reward. It's been a very successful male training technique for her over the years.
