By "sex symbol" I meant something "a famous individual widely considered to be attractive, and a model to emulate for other people who want to be attractive." AFAICT that doesn't really contradict what you're saying. Do you disagree, or do you mean something else by "sex symbol?"
I'm not certain what the general perception of a sex symbol is, but I would guess it includes physical attractiveness and a desire to have sex with the person exclusively for the sexual experience.
That's certainly what I personally associate with the concept.
So, I think I agree with what you really mean.
But it's sort of a grey area, and I'm sure many people would use the term in the same way as you did.
That. But a related point is that men don't (necessarily) stop being sexually attractive once they get visibly old — wrinkles, gray hair, that sort of thing. That's IMO a key difference.
Well, that can go for both sexes. Obviously, we're talking rather extreme generalisation here.
But, if we take Jack Nicholson and Sean Connery - and take their visual appearance today, I doubt a lot of women find them particularly "fuckable" - lacking a better word.
Attractive? Sure.
Sex symbols? Not in my view - but definitely attractive to be with, because if you're with attractive people, the general perception seems to be that you enhance your own attractiveness. Some people even seem to find their own personal value through those they associate with.
Not that I personally agree, but that seems to be a relatively common understanding.
But I think it's safe to say that women are traditionally "conditioned" to go after males with power and importance, and it's not hard to understand why - if we look at the historical division of those things.
As such, it might be less clear when pure physical desire stops, and a more general attraction becomes the primary motivator.
