Believe it or not, but morning boners are very common. Here is one guy who recently woke up with a morning boner.
There is a big question on why guys wake up with erections in the morning. Actually, you can get several erections in the middle of the night when sleeping. This usually only happens in the REM stage and can last even long after you wake up. For those of you who have weird dreams that are not sexually explicit – this is common. For example, you could be dreaming of dirt and have morning wood which some guys think is very weird. During the Rapid Eye Movement stage of sleep, this is when dreaming also occurs. None of this is related to your boner. However, neurological signals cause your body to become stimulated, forcing blood into the penis and which it swells – and you know… that’s exactly how you get a boner. This is called delivering oxygen to the penis and in fact, is very healthy.
