Dolcett is one of the methods of Gynophagia. It usually centers around the main female character of a Dolcett comic being spit roasted alive and enjoying every moment of it.
That is a fetish, a behavior that causes self-satisfaction due to a psychological subconscious association. Philosophically we could pose some questions. First of all: what does the word 'behaviour' mean. Secondly: how can anyone experience 'self-satisfaction' by 'behaviour' and third what is 'psychological subconscious association'? To put it straight: none of these principles exist or have any influence on sniffing female feet. It's just a remnant of gynophagia or eating women. He who sniffs likes to suck and lick and eventually fantasizes about eating woman's feet.
