Perfect 10 as a rough guide.
You can be a size 6 or 4, but only if you are near 5ft tall. Then up to size 12 for nearer 6ft.
That's what I like. But I am only 5'6" so the tall ones happen but only very rarely!
But with curves. Not skinny. Need someone to hold, but not someone who is overweight.
With a great bum comes great legs, so breasts are just an added bonus.
But this is just body shape. I can be set off by someone's smile, eyes, personality etc.
