The sacral nerve, part of your parasympathetic nervous system, controls erections.
The sympathetic nervous system is what prepares you for action — the fight or flight response. The parasympathetic nervous system, on the other hand, is what’s active while your body rests and repairs itself. It’s responsible for things like digestion, getting rid of waste, and sexual arousal.
The parasympathetic nervous system is active when you’re asleep, so erections sometimes happen in your sleep. The term “morning wood” is actually a misnomer; penises can become erect and then flaccid again several times in the course of one night. You’re just more likely to notice it when you wake up.
The challenge is humans really can't access the parasympathetic nervous system while conscious. (At least not that I know of). It's the sympathetic nerves that control sexual response when awake.

Very nice video, yes. Seen it before but rewatched it to refresh my memory.
Still, doesn't explain nocturnal erections.
The nervous system is so damn complex, think there's not much hope for my case :/
