Think of it this way. It's ten years from now and you've finally decided to settle down. You meet the girl of your dreams. Smart, funny, good looking. Then you get serious and she tells you about the 30 guys she banged in college, getting knocked up by her high school teacher at graduation, the six guys from that night at the frat party, etc. Kind of ruins the whole "you're the love of my life" vibe for you, doesn't it? I know if I had to explain to my wife that I slept with 20 skanks in college just to pass the time (or she about 20 guys she had to pass the time) we wouldn't be married now. Hedonism and instant gratification is nice at the time, but there's a price to be paid in the long run that doesn't make it worthwhile for me.
