I think people are missing the point here.
Throughout history, humans have become sexually active in every society by the age of 20. Ironically, it is primitive religious societies in which this is often at the ages of 12-15 through premature marriage.
As societies advance in sophistication, marriage occurs later and later and sexual activity outside marriage increases and loses its stigma.
It does not really matter at all that Pakistan is a theocracy in which non-marital sex is banned. Players are going to get opportunities like their peers overseas, in fact after the pandemic half their opportunities will be overseas.
Currently there are three distinct problems:
1. Pakistan players have generally not been taught to treat western women respectfully, and get into avoidable conflict with them. This includes rape: Pakistani men often consider that in marriage or ongoing sexual relationships consent is automatic, whereas we in the west call that marital rape (and consider it much more of an evil than consensual sex outside marriage).
2. Pakistan players tend to have access to electronic devices which will be used to record the sorts of tryst that Imran Khan had every day 40 years ago, but which nowadays risk being recorded and distributed.
3. Conservative Pakistanis tend to just say "these are the rules of our society" which does not help with men who spend 100+ days in the west every year.
The solution is intensive teaching about acceptable behavior, from junior level upwards, and with a focus not on just Pakistani societal norms but western ones too.
