I read this wonderful little snippet in Mary Roach‘s entertaining book Bonk.
In San Francisco, cock ring emergencies are so common that they have their own shorthand (“C-Ring”) on the Fire Department teletype. The department’s heavy rescue squad has a modified small circular drill especially for this purpose and occasionally stages practice drills. The latter prove challenging owing to the absence of manipulable genitilia on resuscitation dolls and the refusal of male staff to volunteer as mock victims.
The latest cock rings do more than just enhance your erection. The sex counter will also keep a record of how many thrusts (or bonks per minute) you make per session.
