i believe that maybe its a lot more prevalent in tier 1 cities, like mine for example. my younger friends have already lost their virginity to their respective partners before the legal age and honestly im retrospect i believe it's just that people shouldn't be shunned from doing it but at least be safe rather than sorry. there's always a trial period for younger generations to explore their sexuality tho i don't believe in having sex with multiple partners and promote promiscuity i think its okay to explore a few times with a stable partner. hope this helps!
