Feeling generation gap with my generation itself.

So few minutes ago I was scrolling through reddit and for the first time I read a post in sub called indian women.

https://www.reddit.com/r/AskIndianWomen/s/JI1WV1v6Qh

They are saying - expecting girls who didn't had any sexual past is unrealistic and regressive thing to do. And all the people are praising her . But my question is why don't they marry the guy they slept with ?? They will come into another guys life and lie about past.

So is this the mindset of genz of metro city??
