It seems to me there are a number of interlinked but separate aspects here:
1, the condition;
2, the person;
3, the behavior;
4, the social aspects;
5, the political aspects; and
6, the moral and religious aspects.
I do not intend to discuss any of these right now. I only want to point out as strongly as I can that these are separate aspects.
The only other opinion I'll put out now is that I firmly believe that almost any sexual behavior can be an acquired taste. And since human sexual drive is so strong, and sexual activity is so highly pleasurable, that acquired taste can become an addiction.
