Hugh - who has previously dated Elizabeth Hurley and Jemima Khan - admitted he is only just beginning to understand women.
He told Total Film magazine: "I think [women being inexplicable] is the fascination, isn't it? I've got a bit better at it I think, but I'm a late developer.
"I'm 51 and just beginning to see some of the stuff that's going on that we, as men, are generally moronic about."
The actor also claimed he enjoys appearing on 'sexiest film star' lists, but insists they are not his only targets.
He said: "All of those [lists] are pluses. I can't pretend I don't have an ego, and any man would like a bit of that.
"But it's not my raison d'etre."
