The whole "age gap" debate is very western/white coded. The reason it's taken so seriously in white communities is because of how poorly the women age. In a lot of places, the women still look good into their 30s, but because of a diet of goyslop, partying, drinking, coke, casual sex, etc, it ages them and makes them look like shit. Ironically, age gaps are more normalized in Eastern and middle eastern culture while in the west any relationship where the man is 4-5 years older is seen as weird.

Pic related, this "Japanese school girl" was in her early 30s when this picture was taken.
