Hey i got a question..Is the penis voluntary or involuntary? I ask this because:
When we are sexually attracted to someone..The penis errects, which is normal
Yet sometimes it just errects out of the blue. Thanks

I can voluntarily control mine (at least raise it) by thinking of stuff I'd like to pork.  However, it can involuntarily raise even when you're not thinking of that stuff.  It gets hard because blood has flooded the capillaries, which happens when you wake up or when you eat eggs or red meat, which give you higher blood pressure.
