I secretly have a foot fetish
That's normal. What about feet do you like?
I'm into them! They are beautiful to me.
It's perfectly fine to be attracted to someones feet. Even if it's not the most social normal thing there is nothing wrong with seeing sex appeal in someone elses body.
True...
Definitely, and I think that foot fetishes are more common than you think! So you're definitely not alone in this regard. As long as you don't let it out in public, it's fine to indulge in these things that the public doesn't like.
