OCD stands for obsessive compulsive disorder, the prefix in the front, which would be be “p” in this instance, only refers to the kind of themes of the obsession, and the motivation for the compulsion.
POCD isn’t a separate disorder outside the umbrella of OCD. But rather an informal term used to denote OCD which is centered around the fear of being a pedophile. As such, “POCD” is not treated fundamentally any different from any other “form” of OCD both in terms of medication, and even talk therapy.
Having POCD doesn’t mean that person’s a pedophile, and it doesn’t necessarily mean they aren’t a pedophile either. It just means they have an obsession about being a pedophile which they attempt to ameliorate in some way with compulsions.
The dialogue of
" You don’t have POCD , you’re just a pedophile"
And
“You’re not a pedophile, you just have POCD”
Doesn’t make any sense for that reason.
