This is an interesting article that discusses the differences between “love” and “sex” and the different parts of the brain that are involved. One of the big ideas behind this research is that casual sex isn’t so casual. In fact, one third of people who have friends “with benefits” end up falling in love, precisely because of the brain systems with their chemicals and attachment systems that are activated. Love and sex can in many ways appear and perhaps feel the same as an addiction. In fact, the same chemicals and brain systems are at work in both. Interesting stuff!
