People love to bash the DSM and psychiatry/psychology in general for labeling normal behavior as a disorder, and for ever-expanding the list of mental conditions. I'm looking through these and I'm surprised by how many of these are really quite medical in nature (anything neurocognitive, or severe withdrawal symptoms). I wasa little weirded out by how various types of withdrawal are listed with psychological problems, but then again, it could just be a formality.

That said:

Why are these on a list of psychological disorders? These are medical problems.

I'm still not convinced this exists. At best, it's a lack of discipline and boundaries. At worst (and more likely), it's some other disorder or combination of disorders.

How is this different from anything else in the conduct disorder section?

Oh America, labeling people's sexual eccentricities as mental disorders. With the exception of pedophilia (which can actually lead to harm towards others), I don't see how any of these are disorders. What consenting adults want to do in their bedrooms is no one's business, so I don't see it can be a mental disorder.
