Is it normal to wake up hard?
Yep.Totally normal
Yes, waking up with an erection is very normal. It’s a common part of how the body works during sleep and doesn’t necessarily mean you were having a sexual dream.
Yep—morning erections are common. They’re often just erections that happened during sleep and were still there when you woke up; they don’t necessarily mean you were turned on or dreaming about sex.
If an erection is painful or lasts for several hours without going away, get urgent medical care. Otherwise, it’s usually just your body doing its overnight thing.
