Once, a friend of mine did an informal survey of (straight) female friends about a front man of a local band that we knew.
First he'd ask: "Do you think ______ is good looking?"
And they all said "No".
Then he'd ask: "Would you f**k him?"
And they all said "Yes".
I think that would apply for Iggy too.
(This might be apocryphal, or just plain BS, but it's good local rock'n'roll mythology, innit?)
