Likewise, I think what you are referring to is paraphilias that are considered psychiatric disorders.
Although I am no expert, I believe you can have paraphilias that do not cause you distress. I believe there is overlap between fantasies and paraphilias. In fact, if you have a paraphilia, I would practically expect you would have related fantasies.
Wikipedia - Paraphilia wrote:American Journal of Psychiatry describes paraphilia as "recurrent, intense sexually arousing fantasies, sexual urges, or behaviors generally involving:
1.Non-human objects
2.The suffering or humiliation of oneself or one's partner
3.Children
4.Non-consenting persons
So I assume for a fantasy to be non-paraphilic, it would have to fail to meet the above criteria.
Wikipedia - Paraphilia wrote:In the current version of the DSM (DSM-IV-TR), a paraphilia is not diagnosable as a psychiatric disorder unless it causes distress to the individual or harm to others. The DSM-5 draft adds a terminology distinction between the two cases, stating that "paraphilias are not ipso facto psychiatric disorders", and defining paraphilic disorder as "a paraphilia that causes distress or impairment to the individual or harm to others". This will make a clear distinction between a healthy person with a non-normative sexual behavior and a person with a psychopathological non-normative sexual behavior.
likewise wrote:From what I have read, most psychologists now consider S&M to be a normal variation of human sexuality, especially when it is just fantasy.
I believe sexual sadomasochism is no longer considered a psychiatric disorder. However it may still constitute a paraphilia.
But as I said, I'm no expert, so am happy to be corrected.
No diagnosis, lots of opinions, and a bunch of issues that I haven't quite figured out.
