Why do guys just want in a girl? Why?

First off yes all guys are like this, I mean what's not to like about a hot girl? It's a different feeling when you are a guy you want certain things. But it's nature, guys always are looking for someone to bang I mean I am. But the difference between girls and guys is... They have nothing to lose! What's gonna happen? Are we gonna get pregnant? No. And I'm pretty sure that is the reason why girls aren't hunting for like us guys are, the older you get, the more you want it. Then you hit a point and it's all downhill from there. Just look for the right guy. Also, if you are a virgin you will have a different opinion on the subject. Just don't be selfish and use protection ;)
