A man is suing BMW and seat-manufacturer Corbin-Pacific because a four-hour motorcycle ride gave him an erection that would not go away.

The civil suit, filed in the Superior Court of California in San Francisco, alleges the plaintiff, Henry Wolf, developed a severe case of priapism after a long ride on a 1993 BMW motorcycle. Priapism is a medical condition where a penis becomes erect and does not return to a flaccid state.

Wolf claims he rode the motorcycle on a four-hour trip – two hours each way – on May 1, 2010. Soon after, the man claims, he developed a case of priapism. He blames the condition on the motorcycle seat which is describes as “ridge-like”.

The man claims the condition caused emotional distress. Court documents state:

Plaintiff now suffers from priapism (a long lasting erection), and 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. Plaintiff is distraught and distressed because of this. Defendants, and each of them, are liable to Plaintiff due [to] their negligent design, manufacture and/or installation of the seat on Plaintiff’s motorcycle
