SAN FRANCISCO -- A motorcycle-riding California man has filed suit against BMW, claiming that the "ridge-like" seat on his bike left him with a long-lasting erection and unable to have sex.

Henry Wolf alleged that a four-hour ride on his BMW motorcycle in 2010 left him with priapism and "unable to engage in sexual activity," according to court documents filed last week.

Priapism is a medical condition in which the erect penis does not return to its flaccid state within several hours.

In the suit, which was filed in California Superior Court in San Francisco, Wolf alleged that his condition "was caused by the ridge-like seat on his motorcycle, negligently designed, manufactured and/or installed by defendants."

Wolf and his lawyer, Vernon Bradley of Sausalito, Calif., are targeting BMW of North America and Corbin-Pacific, the maker of the seat, in the suit, which seeks damages for lost wages, personal injury, medical expenses, product liability and infliction of emotional distress.
