Human sexual nature is not culturally limited to one culture, Asian, Latin, Russian ECT.
Plain and simple, a man with female friends are friends he hasn’t slept with yet, but is going to try, sooner or later, when the timing is right. Women with male friends are friends who are there for comfort, to lend an ear, a warm hug, and when the time is right, to help them remove their bra and panties.
If your wife or husband is spending time with the opposite sex, you got some problems coming down the road.
