The way that you know them so well and you have truly no reason at all to impress them, understand the things they like or go ballistic with their s*xual dreams makes it less requesting to have uncomplicated s*x with your ex. These things stay steady for both of you as being with a well known body you know in and out is engaging in spite of the way that you have it at the back of your brain that it won’t last. Having s*x with your ex will in all probability not make you get over them, neither will it help you start a fresh relationship.
