“Be aware that abstinence will make you radically reevaluate what sex means. You’ll think about the physical act of it and reassess what an extraordinarily, magically, disgustingly intimate thing it is. You’ll lie in bed at night pondering it, trying to recall exactly what it feels like to be that close to someone and think: I cannot believe I once did that with a guy who wore a pastel-colored sweater tied round his neck in that old European man way and works in insurance and whose surname I don’t even know.”
