Boys vs. Girls

Why are guys so complicated? I have had numerous conversations with other girls about this. Why do the girls that are crazy, psycho and manipulative the ones who get the guy in the end? Why is it okay for men to sleep around, but when a woman sleeps around they are considered a slut? How is that right? I don't understand it. In my life right now I'm not looking for a relationship with anyone specific because of my own personal reasons, but I feel like most guys perspectives on relationships are so different from girls, at least while they're in college. I would love to be a guy for one day and get into the minds of them. Why is it that they go for looks first? If you don't have an ass like Kim Kardashian they don't give you the time of day. I think that's pretty unfair to those of us who don't have a black girls ass, there is much more to a person than their looks. I think its rather funny that guys are pretty simple minded, but come off as such a complicated human being, at least to most girls. The difference is, guys think with their "package," for lack of a better word, I guess; and girls think with their hearts. Why don't any of us use our heads? It's love, it messes with our heads too much, I think. Just some thoughts...take it as you will!
