i always get boners on the bus somehow, and its always just before my stop. i have to cover my cock up with my jacket

The bus definitely can get your shaft cranked!

I hate random boners lol. But I just tuck it in my waist band of my boxers and it's all good lol

yes, the vibrations of the bus get my cock hard too...LOL

I get sympathy erections at the gym. If someone pops a boner i usually sport one at the sight of theirs. I think its perfectly natural, I've seen guys jerk it out at the gym shower its cool with me, just keep it clean.

It seems i'm always more likely to get one for no obvious reason when i'm tired. No idea why that is.

Its a long time since i've had one whilst changing at the gym. Ironically its usually happened because of a wrapped towel rubbing against me and setting me off. If i'm naked and uncovered its never been a problem since I was probably a teenager still.
