Di was an 8.
Kate is an 8, maybe a 9. A 10 if she takes it in the ass.
Megan I'm not a big fan of. She's ok but just doesn't do it for me. A 7.
But really under my own personal system they are all 10's just because they're fuckable.
Horse face on the other hand, I don't know how Charles gets it up for her.
