Two random thoughts:
Overweight guys dont necessarily want to date overweight girls.
Overweight girls in some people’s minds is anything over a size 6. Overweight for guys means more than 50 pounds overweight, not 10 or 20 pounds. Theres a different standard for the definition of overweight for guys and girls.
The ememsdik girls are very sensitive to this and hurt by the above 2 facts.
