“We were young.  The human equivalent of sixteen.  It was, for our complete inexperience, alarmingly pleasing, almost dangerously intense, because we had no idea what we were doing, and even holding hands is completely forbidden in  Time Lord circles, so you can imagine what an orgasm feels like in a touch-starved society to touch-starved adolescents. Physical affection is relegated to the so-called ‘lesser castes’ of Gallifrey, and ‘inferior’ life forms.  But we always found ourselves touching each other physically when we were alone together, so one day alone in the fields of Mount Perdition, we most certainly lost ourselves.  We both wept and we didn’t even know why, not at the time.  We were rubbish at it and yet it was wonderful.
