I'm not insecure about it, I'm a content creator who makes foot worship videos, a lot of my participants trying it for the first time. It's a beautiful thing, and most of them have found they really like how it feels. I'm proud of it and try to encourage others to do so, but I'm aware that it's a fetish many are insecure about. Some adult women don't have much difference in their shape than they did when they were younger, does that mean we shouldn't find people with less curves attractive? No. It's all in the knowledge about the person you're visualizing. You can show a straight guy a picture of a cute girl, then latet tell them it's actually a guy, and they will probably lose all attraction. Brains are weird that way, but it's same thing. Our brain tells us what's ok to like and not, so as long as your head is in the right place, it's not an issue.

You've basically said "Since children's feet don't look that different than adult feet, it's weird to have a sexual attraction to feet". And that's just a really inexperienced take to me. Bodied are bodies, we all have feet, butts, legs etc. Just because children have those things too, doesn't mean we can't find them appealing in other consenting legal individuals.
