Some women absolutely have a preference for shorter guys, but they are rarer.
Depending on your tastes, you could date taller girls who are only chubby. One of them is bound to be barely controlling her weight in hopes of getting a husband and will let go when she feels safe letting go. Women gain weight in marriage. After all, they say that the most fattening food to a woman is wedding cake. It does take a specific type of woman to really enhance the course of nature though.
I was honest upfront to eliminate relationships that wouldn't work. It worked for me. Not the tallest or fattest, but 120lbs gained and counting. Fat girls are bigger in person than porn leads you to believe.
A best friend that I get to bang. I encourage her to workout so she stays mobile and avoid sugar.
