So you split with your ex, and you say you’re really done. The relationship is over. Only problem. The sex was so good you still dream about it. At some point told yourself just one more time will be enough. You both know each other’s bodies better than anyone else, you know how to get each other off and most importantly, it’s feels so good. But is it really a smart thing to do? Do you really get any closure if you keep calling your ex for a late night booty call?
