Not that ridiculous in this era. Women openly drool over hunky men. From Jon Hamm to Beiber to Brad Pitt to Clooney and on and on it goes depending on your taste. They're obviously traditional celebrities.
The only thing unusual about it is the fact that Mayer is in tech where I think the cultural stereotype would be that there are less sexy people because most jobs don't benefit from it or require it. However I've seen guys like Kevin Rose, Jack Dorsey, Elon Musk and Dennis Crowley regarded for various degrees of sex appeal.
Or take a negative example of this: Bill Gates for the entirety of his Microsoft career, was frequently regarded as looking nerdy, dressing badly (early days), looking unkempt, not combing his hair, all sorts of negative descriptives have been applied to him from the founding days forward. Do you think that was detrimental to his career? His start-up efforts? Do you think it kept him awake at night? Did it crush his self-esteem? Did it harm him as a professional? You could hardly read an article about him without them first describing him based on his nerd'ish looks. Gates was regarded as a 'boy wonder' for about the first 15 years of his career, thanks to his young appearance (despite being in his 30's).
The reality is, guys don't get upset when they're ogled for being sexy. It's a compliment. There's an intense double standard derived from the notion that women are not given equal opportunity and are treated in a sexist manner across the board.
On average men and women take sexual advances completely differently, and they take compliments about appearance very differently as well. If you compliment Elon Musk for being good looking, he's not going to think that detracts from his abilities, and nobody is going to care. If you do the same thing to Mayer, you'll create a firestorm; suddenly it's sexist and not being fair to her. Thus a double standard.
Take a bar poll some time about how men and women react to having their ass slapped by the opposite sex, see how those numbers roll out, and that'll tell you most of what you need to know about the difference between the sexes on this topic. Point being, men and women generally react very differently to the same input.
