Often I’m asked how I define thin when I say that I desire only thin women. My answer is as follows: An attractively thin lady to me has a body mass index (BMI) of between 16.0 and 18.5. To put that more concretely, ladies 5′ 7” tall, I prefer to weigh no more than 118 pounds. If she’s 5′ 11” tall, then I’ll be most excited when she weighs less than 133 pounds. There. Is that quantitative enough?
