I lightly addressed the whole 'feet are nasty' idea in the 'Thank You' thread, but I feel like expanding on that idea in a little more detail now. I hear people saying how the human foot is loaded with germs and that they emit a great amount of sweat. I agree that those things are true. However, I would like to compare the feet to a dick for just a moment if you will.
I'm sure that we are all aware that men use their dicks to urinate. Urine contains urea and other substances that can be toxic. Are there any men here who wash their dick with soap and water after going to the bathroom, or do most of you just shake it in the hopes of getting most of the moisture off of it before putting it back in your pants? My guess is that no one is washing it, and it ends up with some small traces of urine on the tip of it when it goes back in the pants.
Secondly, do men wash their hands before touching their dick?? Most germs are transmitted by our hands. So, if a man doesn't wash his hands before pulling his dick out when he goes to the bathroom or when he is readjusting himself, he is basically putting everything that he has come in contact with that day on his dick when he grabs it.
Thirdly, I would say that most men sweat at some point during the day, and their balls end up with some amount of sweat on them. I'm sure that I'm not the only lady who has ever come in contact with sweaty balls while performing oral sex.
I'm sure that I could go on, but I'll stop there. All of these things make the thought of sucking a man's cock very unappealing. I would venture to say that I love sucking cock just as much as most of the foot fetish men on here love sucking toes. Even though I know all these disgusting things, I will still drop to my knees as soon as my man hits the door from work and suck his cock, as Chris Rock would say, like it has the cure to all the world's ills in it.

No matter how many awful things are said about it and what lab results show, I will suck dick until the day that I die because I LOVE it.
It's the same thing with the feet. For whatever reason, we derive pleasure out of it because we enjoy it, our partner enjoys it, or because we both enjoy it. So, if you enjoy it, great. If you don't, great. But don't judge what someone else does because you don't like it. My guess is that you may be doing things that are just as unclean too. You just haven't thought about it in that way because you like it, and you don't want to think about it. Live and let live I say.
