The difference is that USUALLY, girls use some tp or something to wipe up. If that's not available, or she just doesn't feel like it, yellow spots like that tend to show up readily, as panties tend to be made of less robust material than men's underwear.
If they're white, they can also stain that way.
Finally, the non-urinary secretions of a vagina are just corrosive enough that discoloration in line with that can occur over time whether or not a girl is taking care of that.
