Tape or hose on your dick. Also a lot 'rides' on your harness hook. Some brands of harness are more prone to the hook straightening. If it has a real fish hook 'U bend shape on its side', you won't have problems. The hooks can bend open to more of an open J shape. Warm it up in hot water and give it a hit with a hammer to close, if this has happened. Maybe compare your hook bend, and give a few other local kiters dicks a squeeze, to see how bad your problem is!
