Without being judgmental on the hookup culture, I can understand the biological needs of young people that decide to let it all out through intense sexual activities. I was in a college fraternity and understood why it was tempting to engage in the hookup culture. Let's keep it real - when it was mid-night, you had some (cheap) beer and all the people around you looked attractive and by the way, everyone was dancing in a physically suggestive way, you have to be a medieval monk to restrain your sexual urge. So YOLO!

That said, having sex with someone is NOT only a biological experience. It is spiritual as well. Therefore, the problem with hookup culture is that people are binding themselves to one another spiritually without realizing so. This is why breaking off with people that you have had sex with are harder than one might think...
