Yes I have been told its the most common of all fetishes, and I am not completely obsessed with feet or anything but an attractive pair of feet on an attractive woman with a pretty face gets my hormones pumping.
My first memories of this attraction were around the age of 12 (which is when I first remember feeling ANY kind of sexual attraction towards women).
To me the fetish is very embarrassing. I have not had much luck with women in life, but if I did get into a relationship I would likely not tell them/try to hide it because its embarrassing to me, and seems moderately "odd".
I find other parts of women attractive to some degree, but nowhere as strongly as feet, although I am VERY picky about what feet and women I find attractive.
I am not into the "smell" thing that some foot fetishes are, I like clean and healthy feet. I do not mind a mild, normal scent, but highly smelly / unclean feet are repulsive to me.
In my teen years I was lucky enough to have given some very pretty girls some feet messages and this drove me crazy! But I have never had sex with anyone, and I have never had a full sexual experience involving feet (ie having some sort of real sex somehow involving feet as part of it).
I keep my fetish hidden cause of the embarrassment, though I know that only a small percentage of the population would be outraged or think that liking feet is "seriously weirdo". Most people are somewhat more accepting than that I think, but I having low confidence with women I would die of embarrassment touching their feet and having them know it turns me on.
I find the soles / bottom side of the feet most attractive. I have absolutely no idea why, I don't have any memories that would suggest that I was "conditioned" this way. I do not know if it was conditioning or may even be some genetic trait.
I also have a moderate attraction to tickling females / and being tickled by them, though I have never actually engaged in this, however this "fetish" is less strong than my foot fetish and ideally involves the tickling of females feet.
Well I am out the closet now.
