I just read an article wrote by a guy who says that guys want to have sex with all the girls they meet during the day and "while fucking with every girl (in real life or just in our heads), we look for our perfect women. We don't know how to search for the perfect mother, wife or friend so we look for somebody that we're compatible with in bed and then check what other qualities she has. Sometimes is works, sometimes it doesn't. When it doesn't we go back to having sex (in our heads mostly) with every girl on the street. Sounds pathetic but this is what the future of our species is resumed to. I know it sounds extremely sexiest and that a lot of you are disappointed that there is nothing noble and spectacular in your interaction with males. This is the truth. This is how we search for the perfect women. That's all our brain can come up with. Or did you think men are smart beings?"
