48-year-old Brit Catherine Cartwright ignored a court-ordered ban on her noisy sex, and has pleaded guilty to making love with sounds described as "murder," "unnatural," and capable of drowning out her neighbors' televisions.
Cartwright had been banned from her noisy romps after hundreds of complaints. Even her postman and a women who walked her child to school past Cartwright's house complained.
The Press Association reported that Cartwright claimed to not realize she was being so noisy:
Giving evidence Cartwright said she was unable to control the noise she made during sex. "I did not understand why people asked me to be quiet because to me it is normal. I didn't understand where they were coming from. I have tried to minimize the situation by having sex in the morning - not at night - so the noise was not waking anybody," she said.
