If we admit that homosexual obsessive compulsive disorder (HOCD) is a psychological problem, then we shouldn’t eliminate the possibility that any psychological state can have an impact on our symptoms: When we’re happy, sad, tired, hungry, horny, angry, lonely … all of these could affect symptoms.

Behavioral scientist Steven Hayes and his colleagues have found that “experiential avoidance,” that is, the inability to allow uncomfortable thoughts and feelings to stay there without attempting to getting rid of them, contributes significantly to psychological problems.
See their book, Get out of Your Mind & Into Your Life (2005):
It’s like they were saying that the desire for a cure for HOCD is part of the problem.

We could add the psychological state “wanting to be free from HOCD” to our list (happy, sad, tired …) of states that could affect HOCD.
If we accept the idea that HOCD is partly psychological, then we at least can’t eliminate the fact that the psychological state of “wanting to be free from HOCD” could be contributing to the problem.
From personal experience, in a paradoxical way, when I stopped wanting to find a cure for my HOCD, it started to go away. I outline all of this in my book about HOCD recovery: http://amzn.to/2mdtR81
