Dear Amy: Everyone claims that college is the best four years of your life. My friends always pressure me by saying that I only have a limited opportunity to go wild and have fun. Recently, I have been having a lot of one-night stands and really casual sex. The moment I realized how damaging this was for me was this past weekend where I hooked up with a guy who I thought was super-cute and honestly would like to get to know better. The next day a group of us (including him) hung out.
