The bodybuilder known only as "Charles" is suing Montreal firm HotGVibe in relation to his 2009 purchase of the X4 Extender Deluxe Edition penis enlarger, The Examiner reports.
According to La Voix de l'est, Charles claimed in court earlier this month to have used the machine for over 500 hours before giving up.
"As I am a bodybuilder, my body grew and I wanted the rest to follow", he reportedly said.
The plaintiff is suing for the $262 (£165) price of the contraption in addition to $500 (£315) in moral and punitive damages.
Describing the sensation when using the machine, he added: "It's extremely painful - a feeling of suffocation."
The X4 Extender Deluxe Edition features complete spring-loaded assembly, hybrid support system compatible with silicone harness and comfort strap technology, memory foam comfort pads, two specially calibrated tension strings and a full set of extension bars.
