My uncle has been going through this. Commuting in the car, plus at work, strong quick urges to do a wee - almost to the point of getting caught out a few times!
He went to the Doctor > Hospital and was diagnosed with prostate cancer!
He's just recently had the main operation, to get the cancer removed, and is currently recovering in hospital as I write this.
It's the most common form of cancer in males in the UK and it's a sensible choice to book an appointment with your local GP if you have concerns (speaking to the masses here). Not trying to cause any concern to you Fazerider, plus hopefully your case is nothing sinister, however reading your Post immediately related me to my uncles current situation.
You'd expect cyclists to suffer from your symptoms Fazerider much more, as their saddle is nothing (literally) compared to a motorcycle seat, which is far more supportative plus substantial. <<<< After writing that, I see you mention it also in your last post. Agreed.
