Based solely on looks, my scale is this:
1 - A handful of the ugliest women on earth
2 - Extremely ugly
3 - Really ugly
4 - Ugly
5 - "Lower Intermediate"

6 - "Upper Intermediate"
7 - Cute
8 - Beautiful
9 - Stunning
10 - A handful of the best-looking women on earth
When I'm REALLY drunk, I can go as low as a 4 (I once fùcked a 3... I was extremely drunk). When I'm sober, I can fùck a 5 only if nobody else knew about that. I could have a serious relationship only with 8s and above. If a girl has an incredible personality that enchants me but she's a 7, I'll take that too. The girl I'm in a LTR with is at the moment a 7, but when we hooked up she was at least a 8, in my book.
I've never met any world-class stars in person, so I can't tell how good they look in real life. Anyway, Britney Spears, 4-5 years ago, would have been a 10 to me, now she's a 6.
Shakira is around a 8.
Uma Thurman is a 7.
Elisha Cuthbert is a 9.
Most younger porn-stars are 9s and 10s in my book, but I love young-looking big-titted green-eyed blondes and most Bunny Teens are like this
