To be honest, I had always learned that men wake up with an erection in the morning because they need to pee. I don't usually cite wikipedia but for lack of a better source:
"Evidence supporting the possibility that a full bladder can stimulate an erection has existed for some time and is characterized as a 'reflex erection'. The nerves that control a man’s ability to have a reflex erection are located in the sacral nerves (S2-S4) of the spinal cord.[3] A full bladder is known to mildly stimulate nerves in the same region. This mild stimulus which during the day is normally suppressed in adult males by competing stimuli and other distractions; during sleep with the absence of such factors could instigate a reflex erection".
Now, I would imagine many men upon feeling this erection think they are hard because they are horny. I think that while this is possible, it is more likely their bladder is full
