Maybe for some I guess. I didn’t need one to cool the jets down, it happened on my own. Then my wife and I got together. I am a firm believer people shouldn’t get into serious relationships until their 30’s or whenever they are mature enough to do so. Relying on someone else to help you slow down is unhealthy and could lead to potential issues. Everyone is different and no two scenarios are the same, some folks need it, but psychologists and studies tend to paint the same picture.
