Let's reverse the question: would you still see your favorite curvy/chubby/bbw SP if she had a significant weight loss?
This is a question I'm curious about.
Though I think it doesn't change too much, because once the skin has been stretched to a certain point, the extra doesn't just disappear unless surgery is had.
I'm more self conscious at a lower weight and softer body these days than I was with a firmer more filled shape. But I think the people I see care less about if I fit in a size 16 or 12. They care that WHO I am remains the same, and have benefited from increased flexibility, and more stamina.
Weight goes up and down normally in life. My own lifetime as an adult my lowest was 150lbs (when I was a top choice agency girl at 18-19, and always being picked 1st in lineups 2002), and my highest was 290lbs (during my 2nd pregnancy).
Just over the last 3 years it played around between 175-205lbs. Then again, I don't know how much my sweeties even noticed when it dropped. What they like is still there, just more dramatic deviations, smoother curves, and easier to grab what they like as it softens and the size is less filled in.
