I was a bus driver for 5 years in my mid 20s and I often got a hard-on whilst driving. For some reason, if I'd started work very early in the morning and was feeling tired towards the end of my shift - say midday - I'd get a real stiffy which would make a big tent in my (loose fitting) bus driver's uniform pants. It didn't matter too much going along, but when passengers boarded the bus and queued to pay me for their tickets it was very difficult to hide it as it strained to push up through the steering wheel! I would do things like spread my newspaper on the steering wheel (as though I had time to read it before setting off again :tongue
but I didn't always have any way of hiding it and a few times I noticed that it was being stared at by a wide eyed passenger - usually young and female
I can remember discussing this topic in the bus driver's cafe' and several of the guys admitted that they got hard when driving - we put it down to the low frequency vibrations.
Low frequency vibrations? Yeah, too much like sexual intercourse stroking perhaps? Penises can be supersensitive to rubbing or moving at certain frequencies.
But another factor that quite many people may not even think of, is the rising world population size, and the human race seemingly effectively becoming denser in the big cities. That may increase the apparent need for "sexual relief," attracting people to mate (and marry first hopefully) with so much "breeding material" often so close by, as buses or classrooms and such, are often full of people, with no apparent escape from the natural press of the hopefully well-behaved populous masses.
In the past, noticable erections in class at school, would perhaps have been more rare, because school didn't last all day, and guys often were outside where they could disappear for a while, and not be missed. Now we coup up so many people in crowded co-ed classrooms or cubicles, for much of the day.
Of course I am in favor of so many people being alive, and welcoming world population size to rise naturally unhindered, so that all the more people may experience life, so surely intelligent humans can just "deal with" some spontaneous natural hard-ons.
