Asking a woman to gain because you like larger women would be like a woman asking you to have a sex change, because she likes you, but prefers women.

Asking anyone to change is very risky.

I was a fat kid. While I am not all that big now, my man boobs remain. I am a 38B. If any women is interested in them, write to me.

Hi.

You should gain weight because you like it, not for anyone else.

But anyway. People hit plateaus. If you keep at it, you'll gain to any size you want. I know people who were stuck at 300 who are now well over 400. be patient.

Diets is what make people fat. Let her diet, because in the long run she'll be fatter than ever.
