I know brad pitt is a good looking dude and I know he is sexy.
Do I THINK he is sexy even "objectivly"?
No, honestly I don't.
So to answer your question, when a woman or a man tells me a man is sexy
its not like I don't believe them
but if someone didn't point it out I wouldn't notice.
If a bunch of chicks flock to a guy as you put it because he's sexy....
my pointer would be the flock of chicks.
Chicks and people magazine tell me brad is sexy.
If I didn't know of brad, and saw him somewhere I would not think of sexiness
when I met or saw him.
