curious Actually, both masochism and sadism are still part of medical diagnostic standards, but today there is one critical element that must be present for this diagnosis to actually apply: the person must feel that he/she is actually suffering from having these feelings. If you have either masochistic or sadistic urges but are completely fine with that, the medical diagnosis criteria are not met.
Regarding masochism. What you write applies under the DSM-5. Masochism is no longer a disorder according to ICD-11. From the old category of "sadomasochism" (in ICD-10), only "Coercive Sexual Sadism Disorder" is left (code 6D33 in ICD-11).
As for sadism, it can be diagnosed in both classifications not only if it disturbs the person, but also if he or she takes actions under the influence of this disorder that pose a threat to other people (this applies mainly to sex offenders).
a_father I think one example (@Angelina) that doesn't match would show you, your theory isn't perfect (but definitely appropriate in some cases).
First, I clearly wrote that it is a HYPOTHESIS, that is, something that can be confirmed or disproved. Secondly, I pointed out that it concerns the "large part of the girls on the forum", not "all" or even "the majority". You, on the other hand, provided a good argument against my hypothesis, for which I am grateful. ๐
