That's an interesting (though pretty apt) way to think of it. I hadn't considered that.

lol We could probably have a whole new topic on "Your views on fetishes/sex/more applicable word here."

On the subject of urethra's through, I remain skeptical, though I've been plenty wrong before. It's a very thin tube with quite a bit surrounding it. You *MIGHT* be able to feel the faintest hint of it while limp if you were to, say, grasp it (lol though your partner might have mixed feelings on you hunting for his urethra unless you very skillfully hide what you're aiming at ), but I think it'd be nigh impossible while erect.
