Discussion Main / Dismotivation

I'm a bit confused by the Discworld examples. The trope description is basically that on some level the character has a goal, but on another level they think it's too difficult so they don't try, or outright sabotage themselves. But there's no sense in which Rincewind, for example, wants to go on adventures. He is positively motivated to avoid adventures, but that never works out for him. In a way, his Dismotivation moment comes in The Last Hero; he finally accepts that his status quo is that he goes on adventures whether he wants to or not, and he might as well give in.

Why in the world is the very first point under Real Life something about sexual fetishes? Am I missing something? Because it seems to have absolutely nothing to do with this trope at all.
