men can get erections several times a day through no fault of their own, 'morning wood' stems from your brain shutting off a neurotransmitter that produces a chemical called norepinephrine which controls erections and decreases as you go in and out of REM sleep. When you wake up with morning wood it's usually beacuse you woke up in the middle of REM sleep. Of course it is also a reflex to prevent you from peeing the bed in your sleep.
