I stopped getting spontaneous erections during the day around 23ish. At the time, I was actually really happy because those erections can be kind of embarassing. I thought it was just a natural part of the again process. After talking to some friends in the mid-to-late 20's, they told me they still get one once every week or two.
I'm 30 now so I haven't had spontaneous erections in 6+ years. Should I be getting them or does it go away for some people?
