It can happen for many, different reasons or for NO reason at all. Guys get erections from the time they are little boys. 99% of the time, it was for no known reason. It just happens. A lot.
It may be hard for you to understand that, but guys dont need a reason. It happens on its own.
I started masturbating in a shower and then had to quit that. Everytime it clouded up outside I got an erection!
Some guys do if the wind blows just right. There is no single formula.

Guys can get excited over mental images.... If not, then there's something wrong with him.
The penis has a life of it's own. You can't control it and you don't know what would cause yours to erect.
Some times when the wind blows just right a guy can get hard.
