A listener calls Sex Lives with a harrowing story about accidentally destroying her husband's penis with Lysol, and Maureen enlists Ask a Clean Person columnist Jolie Kerr to help her sort out the ensuing mess. Also up for discussion: sex stains, masturbation messes, sexual etiquette for houseguests, and a theory about why Oscar the Grouch would make a great husband? To leave a voice message for Sex Lives, call 646-494-3590.
