I knew a girl whose ex boyfriend had custom made stilettos just for him.
He would wake her up in the morning asking her to spit on him.
One time he told her to wait 30 minutes then come into the bedroom.
She said the 1st thing she noticed was an electrical cord leading into the walk-in wardrobe...he basically put a small heater in the wardrobe, slid the door shut & tied himself up, wearing the stilettos.
And for the next hour or so, he insisted that she bang & kick on the door yelling abuse at him while he whimpered & cried.
Mother issues.
