Foot sniffing

Can foot smell cause sexual arousal? For specific men, yes. Olfactory stimulation can indeed cause sexual arousal. Also, sweat may contain pheromones and trigger sexual arousal. But is this true for foot sniffing? A test must be conducted: foot sniffers must be exposed to male and female socks. What if they get aroused by male socks? That will prove that their arousal is totally cognitive. Also, if it is about pheromones of sweat, why not get aroused by other body odors? from armpits for example? For these people foot smelling may evoke memories of their first erections. Or by enduring the foot smell of their partner, they masochistically believe they endure for their love. Also, they may just use the smell in order to fixate their attention and thus trigger erection. Or maybe sniffing the foot smell indicates a more intimate contact with the partner, since they are used to this smell when they remove their socks and go to bed. Anyway, they don't harm anybody, it is a harmless fetish, but if become obsessional it is dangerous, also it may be a precursor to an extremely disturbing fetish, femdom.
