Now that we have all agreed that the "perfect" man doesn't exist, and that you can only speculate about a celeb's personality... Here is the man that would come closest to being "the perfect man" for me, based on his looks, his voice, his behaviour, his talent, and the general impression I have of his personality:
Takeshi Kaneshiro : Obviously gorgeous, very talented, and yet also extremely unassuming and humble, even quite shy. From his interviews, he seems to be a subtle and profound character, with an inquisitive personality, who always tries to dig deeper and see if he can take his acting to another level. He seems aware of his beauty and charisma, but not vain, and (sadly for his fans who spend a lot of time waiting for new movies) he does not have much ambition, except the ambition of doing his job well whenever he does accept a role. And he speaks 5 languages which I think is quite impressive.
As I have already said before, I am also very partial to Ben Barnes. I do not admire him as much as I admire Kaneshiro, for he is far from having achieved as much as an actor, but I really find him endearing. He is rather like Kaneshiro in some ways : he also appears as a shy, humble guy, with a quiet personality and a keen intelligence. He speaks well, he is witty and very agreeable. One thing I really like about him is that he does not try to act like a "bad boy". He is a very down-to-earth, polite and well-bred guy, which is often regarded with contempt in show-business where a star is supposed to have a history of antics and scandals in order to be seen as deep and interesting. But he is comfortable with his very clean image, he's rather be called boring than behave like an idiot to attract attention, and I appreciate this.
Now, of course, David Ferrer could qualify as my ideal man too. He became my favourite player way before I got interested in his off-court personality at all, but as it happens, when I did check out interviews and stuff, I liked everything I found.
Among older men, I really like the charisma of someone like Liam Neeson, though I know little of his real life personality. Another man I could easily have fallen for was a young Eric Idle (obviously now he's way too old for me, but I really love this guy's humour and personality).
In short if I try to think of an "ideal" in general... I guess I'd like a man with an inquisitive mind, who is curious and respects knowledge and education, who has at least one talent that I can admire (whether he's an artist, or a sportsman, or an intellectual), who is confident enough (insecure people are difficult to live with...) but not over-confident or cocky because that leads to arrogance and mediocrity. I know I cannot be with someone who is desperate for affection and needs to be constantly reassured, because I cannot give them that, and I'm not looking for that either, so I guess a man who would be aware of their worth while being able to stay humble would be my ideal man. I would also need someone who has no problems with gender equality. It's not a problem for me if a man makes little money, but I need to be sure that it's not a problem for HIM if I make more money than he does.
