Well?
I remember years ago reading a book called the Book of Lists, which listed the 10 things women found most attractive in a man. I googled it but can't find it, so from memory these are in the rough order that I recall.
Sense of humor
Intelligence
Sincerity
Eyes
Kindness
Smile
Flat stomach
Hair (texture, not length)
Buttocks
Legs
Chest and shoulders
Penis
Yes, I know that's more than 10 but wtf, it was 30 years ago. Also, this was in the 1970s, so things may have changed.
What I did find on Google was this Yahoo Answer on 'Yahoo UK and Ireland'. Remember, these are British women, many of whom may still be traumatized about the fact that I'm now living in America.
