Is it normal that i stare at feet alot?

I like staring at a sexy girl's feet so much that i look at them all the time to the point where i imagine myself making love to them!! I love staring at some feet and try to picture those feet in my visions so that i can even remember them well because they are just so sexy to me, esp. if the toes are long w/ either a pink or a french pedicure..
