@Duribu That's untrue though. In the developed world the average age for the loss of virginity ranges from 17,5 in Austria to 22,1 in South Korea according to the latest studies. In Japan it is 20,4, meaning that of the partners who have graduated high school by up to two years you're more likely to encounter a virgin than not.
In the first place the fact you make it an absolute "they're not going to be a virgin" would be wrong in any and all scenario, as even in the most fantastical Huxleyesque dystopias it's unthinkable there wouldn't be at least one person not following the norm. But even if we gave you the benefit of the doubt and assumed you meant "most people are not going to be virgins", that's still patently false. Even in Austria with the average being below 18 you are most definitely not unlikely to find a virgin after high school.
As an added point, as I'm sure someone might claim that this data is old and people are now more open about sexual relationship, let me tell you these statistics I cited come from a 2012 study and that more recent inquiries have found that the new generations are becoming much less sexual than the previous.
