ELI5: Why does athlete's foot only happen to your feet?

If it's a fungus, why couldn't it grow in, say, the webbing between your fingers, or behind your ears?

It could if those areas were damp and warm enough. Athlete's foot only happens to the feet because if for example it is around the genitals it is "Jock itch". Conceptually you could have it in other areas of the body but they would lack a similar name and just be "a fungal infection behind the ears" or something similar.
