Guys I have a serious question

I’m from Noida, and I’ve noticed that many people I know took admission in Graphic Era during 2013-14-15-16. Among them, the boys came back just as they were before, but the girls seemed to become very open-minded and, in some cases, had a more 'slutish' kind of nature. Is there something in the atmosphere of GEU that causes this change? As I know there upbringing from childhood and values that their parents teach But now they are totally changed , being with a guy just for S*x is next to normal for these.
