Everyone knows that prom exists for one reason: to hook up with your date. But it can definitely feel like that if basically alllllll of pop culture is anything to believe. After my first prom, my date - who was my boyfriend at the time - and I went back to my friend's house. I think there was this unspoken vibe between us that we were going to have sex for the first time, but I got really nervous so I drank a bit, and smoked a ton of pot. My boyfriend was dead sober.
