When I wake up in the morning, I often have an erection. Why? That’s a very good question, and im sure many others are wondering the same thing. Waking up in the morning with an erection, is commonly known as morning wood, although the scientific term is Nocturnal Penile Tumescence. And is actually a very common thing, amongst most men. The main reason for “morning wood” is not physical stimulation but is due to the fact that your testosterone levels are at their highest, in the morning, after waking up from their REM sleep stage. And although it may feel strange and uncomfortable, just remember that everyone goes through the same thing, and it’s a part of growing up. If you have any other questions, regarding this issue, my door is always open, and if you don’t feel comfortable talking to me about it, be sure to reach out to your parents or another trusting adult.
