Henry Wolf, who named BMW North America and Corbin-Pacific Inc. last week as the defendants in his San Francisco Superior Court lawsuit, alleges the "rigid seat" of his 1993 BMW motorcycle caused him to suffer a priapism -- a long-lasting erection -- May 1, 2010, and he has been suffering from the condition ever since, the San Francisco Chronicle reported Tuesday. Advertisement Attorney Vernon Bradley said Wolf "has been experiencing continuing problems since his motorcycle ride." "He is now unable to engage in sexual activity, which is causing him substantial emotional and mental anguish," Bradley wrote in the lawsuit. The suit alleges Wolf suffered wage loss, hospital expenses, general damage and emotional distress as a result of his condition.
