Lol, yeah I'm not sure how you reach that decision. BTW we never catch anything out of the corner of our eye at the urinal. If fact I'm fairly certain you go temporarily blind when using a urinal.
It hurts to look at that. The arousal thing is an interesting thought. It would suck if it looked a wonky when it should be ready for action as it were.
I had a 68 Triumph Bonneville and a 96 Triumph Trident for about ten years, but I sold them both. I have a fun car to play with but no more motorcycles.
