Sartre's relevance or value depends on the relevance or value his arguments, not his age or affiliations or sex life. It happens that I think he was full of steam, but it wouldn't make him any better simply to be a woman, or young.
I think what I was trying to get at is that when I was younger, I looked up to certain bearded "wise men" and professors as archetypal "guides" or role models or whatever, but that was a mistake. Now that I am a bit older, I realize that it was wrong for me to look up to such men while ignoring others because by emulating the "wise man" directly I might have "skipped" a very important stage in a man's life: adulthood, when you're strong, aggressive, competitive, and otherwise awesome.
It is my philosophy that one should go through all stages in life in order, otherwise one will never be happy, though timing is not as important as order. I've seen old people get bitter and resentful when they see youth partying and going out -- because they themselves had never done so when they were young.
One of my favorite quotes from Nietzsche (though this guy also had a messed-up/nonexistent sex life): "Man is something to be surpassed, but only a buffoon thinks that man can be overleapt." Surpass but don't skip.
