I'll probably get some hate mail for writing this.
I will comment on HWP because of my experiece thus far with using the words "height-weight-proportionate" on the swinger sites we use to describe what we are looking for in couples.
It was, we felt, the diplomatic way to let people know that how others look physically--in regards to weight--does play a role in how WE are sexually attracted TO someone.
Yet, with HWP mentioned, we still kept receiving introductions from people who were considerably overweight and not well-proportioned or physically a turn-on for us. So I agree with Weezie, it doesn't do much good to use the term.
We have recently made a rewrite that says: "We are not attracted to overweight people." We'll see what happens.

let me add that this is a prerequisite made soley on our sexual preferences (not friendship requirements). I would imagine some of you seek out playmates that have certain physical attributes as well.
