Is it healthier to "cure" or alter such a desire as unhealthy, or to accept its nature/causations and submit to it? (One of the disagreements between jung and freud lay in the application of psychotherapy beyond understanding the causes of people's behaviours)
Every rule has exceptions. It's what makes the human moral landscape so complex and fascinating. I think the concept of "the golden rule" is the most basic, and easiest to understand, of moral principles (it's one of the ways we try to teach our children).
In your example, it depends how you frame who's doing what and to whom. Is it immoral to inflict pain even if the recipient wants it? Is it immoral to deprive someone of the right to behave in this way if it harms no one else, even if it might be viewed as maladaptive.
As another example, I don't particularly liked being picked up and dumped in a swimming pool. My kids, on the other hand, love it. To use the moral principle of the 'golden rule' I might be seen as doing something I wouldn't like done to me. Or I could be seen as facilitating the enjoyment of others - something that I appreciate when done for me.
