Foot fetishism is surprisingly common. It is the most common fetish of the non-genital body parts and non-sexual objects. Sigmund Freud offered the explanation that people develop this fetish due to the fact that the human foot resembles a penis.
No matter what the reason, foot worshiping is a popular fetish with 90 percent of the fetishists being male. It can involve the foot alone or feet, shoes and socks or stockings. Perhaps it has to do with how we are wired, with our brains reacting to different pleasure centers on our bodies. Even individuals that are not into this fetish may enjoy having their toes sucked once in a while.
