      I can not answer why, but I’ve been told I do it too.

      And wake up holding my junk a lot of the time.

      A lot of the times it’s definitely to reposition balls.

      So sometimes not because it’s comfortable per se (and it is), but because doing it avoids possible discomfort, I guess.

      Also, morning wood. What’s that about? What’s the benefit of getting an erection when we wake up? O.o

        morning wood

        When we sleep our body releases hormones that encourages blood flow in our body. Better blood flow means boner.

          Yeah this is an answer I’ve heard, but it’s sort of generalised.

          I’d like a every detailed medical explanation on why it happens specifically when waking up.

            It’s the wrong answer. Also, it’s not just when you wake up - it’s at various times during the night. The real answer is the sacral nerve: https://health.clevelandclinic.org/men-get-morning-erections-5-answers-questions

            You’ll notice them in the morning most because a) you’re awake and b) you’ve had several hours for your bladder to fill, probably enough that you need to relieve it. This puts physical pressure on the sacral nerve, causing the erection. In turn, the erection closes the sphincter to the bladder more tightly because getting urine in the vagina during sex would change the pH and possibly kill sperm you have deposited/will deposit, which makes not tightening that sphincter an evolutionarily disadvantageous trait. This does make it something of a self-reinforcing cycle, though.

              Well yeah, it’s just during the night in general. Hell I’m not even awake in the mornings, lol.

              Exactly what I was asking for, thank you.

                Glad it helped! For what it’s worth I always thought it had to do with vasodilation, but I decided to double-check before posting 😅

      I think it’s common, but not universal. I sleep on my side hugging a 2nd pillow. That’s the most comfortable for me. When I wake up in a weird position, it’s on my back with arms splayed out like a gunshot victim.

      I’ve never consciously done this, but I have woken up many times in such a position so, I have no idea it must be some instinctual comfort position

      I sleep weird, on my side, top leg extended forward parallel to my torso and bent at the knee, and bottom leg straight as to follow my torso. My foot of my top leg is often positioned touching the upper part of my bottom leg as to make a triangle.

      In maintaining this position I find my manhood is free, in failing this I often cup.

      Reason why: its uncomfortable to have my privates sticking to my legs, or squished between my legs

      Also I sleep nude might help explain the weirdness.

      In the rare occasion I wear something to bed, I’ve never done this. If I’ve done it in my sleep, I don’t recall waking up that way or anyone ever commenting on it. My wife will sometimes sit with her hand in her pants on the sofa, kinda like Al Bundy.

      Sweat. When it’s hot and humid in particular, a little bit of lift prevents uncomfortable sweat buildup where the scrotum meets the legs.

      Don’t think I sleep so, but do it after waking up for sure,

      As to why - no idea.

      If you have a guy in your life that you are intimate with, try it out. Hang out on the couch cuddled up to him and give the boys a hand cuddle. You can also do him a favor and check for lumps while you are there.

      Using your belt/waistband is a comfortable and good way of stopping your arms dangling and flopping around while you relax/sleep.
