Wouldn’t the night erection and the need to urinate erection be caused by the same muscles relaxing and allowing blood flow to engorge the cc until fully erect? I am thinking they are one in the same process but with the exception from added bladder pressure in rem sleep pushing on the pelvic muscles. Since the pc muscle is responsible for holding back urine and priming the erection, the blood flow from the subconscious squeezing of the pc causes the hard urination wood. If an erection happens between 83mm hg (3.23in hg) to 106mm hg (4.17in hg) in the penis I guess we will never now the difference unless someone does a sleep study with a bp cuff cockring.
