Because of patriarchal social conditioning which makes people believe man should be older, look more dominant and mature and woman should be young, docile, childlike, vulnerable.
Even young women are judged based on their looks which is why we have topics bashing Madhuri and calling her too old for Khans despite being around same age as them.
I had heard people calling Sara as old looking or too old to debut. Even at 23 she was being called mature or too old for debut.
I find it paedophilia type thinking to admire much older men and want women to look or sound like vulnerable or innocent girls. I have seen people judge Sara's voice for example.
Or call Vidya Balan as 'too old' even when she did Parineeta.
Conversely men get mocked or made fun of if they do not look old or mature. For eg Aamir was mocked and called chocolate boy, bachchu, 'not hero material', not macho enough and only good for college kid roles all through 90s. He was rejected when he did Baazi. Salman was also called too boyish when he did MPK, HAHK. Salman and Aamir had to do tapori type roles in Rangeela, Judwaa to break those stereotypes and prove they could do so called manly roles.
Tiger was also mocked for looking like his mom or compared to Kareena and not being as rugged as his dad Jackie and he had to grow facial hair and build bulkier frame to change that image.
It is conditioning through pop culture, literature, society and age old tradition of even kids marrying older men and generally men preferring to marry younger women and society not even preferring to marry woman of same age to the man of her age, which has led to such conventions that man should be older or woman should be younger or man should be dominant and leader and woman should look coy, submissive, in need of protection.
Heroines rarely had strong roles either. They were mostly damsels in distress and it is hard to show an older woman as damsel in distress or clueless or as innocent as some lost in the woods type little girl in need of rescue by hero. Hence that bias.
Also, there was no tradition of polyandry but widely practised tradition of polygamy due to which, women do not find issues with finding a married man with kids or older age attractive but men begin to dissociate from older or married actresses with kids. Society also judges women more harshly compared to men. For eg no one will judge SRK for kissing Anushka in Harry Met Sejal but Anushka or Deepika will get judged if they do romantic or sexual scenes and Madhuri will be ripped apart if she kisses a 2 decades younger actor. Tabu was also mocked for kissing Ishaan in web series.
Sexist society never asks what will family of man say if he kisses or holds hands of others or reveals his body but will bash women or ask how their husband, in laws or kids tolerate it or mock them or call them MILF or aunty or despo for still acting, dancing or dressing or doing make up or doing intimate scenes or even working or being ambitious.
No one judges Amitabh for working till date as much as they judge women working in older age and call them greedy or addicted to limelight.
Finally women are mostly eye candy in films. No author backed roles at all. Heroes still have better roles, author backed characters and stories tailor made for them. A TZP could be made showing female teacher too. But such roles are not given to women. Whereas men even play college kid or newly married man at 70 and use dozen special effects to look young.
If woman is mainly known for looks, innocence or sex appeal or dance, then how will she be accepted after a certain age?
Society is sexist and judges men far less for botox or plastic surgery as much as they judge women for getting work done or their pics being Photoshopped. We should change things from our side first. I am happy there are couples like Vicky and Kat, Arjun and Malaika, Ash and Abhishek where woman is older. I hope more stories of older woman, younger man are shown onscreen and accepted in real life. I also hope women also stop judging other women and calling them aged in 20s itself and stop lusting after men who are 50 plus raisins. Start welcoming younger heroes. On TV also it is a shame that oldies like Ram Kapoor and Ronit Roy used to romance girls as young as 17 YO Prachi Desai and serials got top ratings. Whereas till date only 2 serials have been made where heroine is older than hero.
