A friend recalls the Cambridge contemporary who pleasured his librarian girlfriend so deafeningly that a staircase neighbour left the following note pinned to his door: "You may be enjoying your sex life, others aren't. Keep it DOWN." Unfortunately the perpetrator wasn't chastened so much as proud that the note's author lived a whole two floors above him.
But then, as Ms Wale's neighbours have discovered, corking a screamer can be a Herculean task. One old pal swears by timing the offending act, from first moan to climactic howl of rapture, and then slipping a note under the offender's door that reads: "Congratulations! You lasted 14 minutes and registered 95 decibels - roughly the same volume as a French horn."
Another friend was bedevilled by a neighbour in a hotel who kept beseeching his inamorata: "Show me your po-po, show me your po-po!" After half an hour, he was about to intervene when he was beaten to it by a still more irate guest, who yelled: "Just show him your damn po-po and we can all get some sleep!"
My worst memory of intrusive rumpy-pumpy came courtesy of a woman in a Parisian hotel, who yelped and groaned for six solid hours. I nearly phoned emergency services, bearing in mind the Seattle woman from the reality series Sex Sent Me to ER, who "suffered" a three-hour orgasm. In Paris, however, it seemed likely that she might be in the running for the Legion d'Honneur for such effusive copulation.
In such circumstances, it's restorative to bear in mind Meg Ryan's skilful faking of an orgasm in When Harry Met Sally. She who moans loudest generally moans most fraudulently. Perhaps then it's as well that our great national institutions (boarding schools, the Armed Forces and HM prisons) have trained inmates to reach the heights of pleasure in tremulous silence.
Many lovers are so mortified that anyone in a 10-mile radius might overhear their lovemaking, they swaddle metal bedsteads in towels to prevent unseemly squeaking. They know discretion in love spares the hearts of the lovelorn, and is more likely to be genuine too.
