Hi there! Pulling....? As in, device pulling on your testicles...? If it's this it's often due to ill-fitting cage.... If a cage is too long and there's extra space in it when you're flaccid, then when you get erect that space fills and this is a common cause of the 'pulling.' If this is not what you mean, please would it be OK if you clarify...? Kindest regards. J.
Your body will become used to the restriction and you won’t become as hard as you used to. In the mean time tight fitting underwear might help.
As far as I know the Nub is a very small cage and so is unlikely to permit any growth - day or night. What might be happening is that as you grow the ring is being forced down onto balls. If that is the case then the answer might be a waist strap to hold the ring against your body.
Drink less before bed to help with morning wood. Often it's caused by a full bladder. I like a bigger diameter ring for night time as a smaller one will dig in if you get too hard in your sleep.
This is probably the best advice in addition to having a good fit. When I get woken up in the middle of the night, I immediately go to the bathroom no matter how little I think I have told go (rather than lying there mentally fighting the erection and pain). Almost immediately during/after peeing, the pressure starts to subside and I can get back to sleep no problem.
I’ve been curious if the micro chastity devices made the nocturnal erections harder to deal with. I have a snug fitting cage, diameter wise and haven’t had a single problem with the nighttime erections. Usually, it doesn’t even wake me. I think the cage stops them right away. But, with the micro devices, you simply turtle and have no cage really to counteract it. I saw a photo of one guy wearing one with an erection. It was a full-on behind the device and pushing the base ring far away from his body. That has to put a lot of pressure on your balls.
I am/was a bit over 7" and I wear a micro cage. What I do is stuff the penis in on itself and put the shaft skin into the cage portion. This way, my penis shaft is up inside my pubic mound for the most part. The cage/ring gap is small enough that despite having the largest (Chinese metal cage from Amazon) ring, I haven't had a ball escape, or nearly as much chafing from too tight a ring. The trouble is that I have to take the cap portion off to pee. I've pondered going to a more open end design to be able to pee, but I usually sit, and I never play with it anyhow, so it's not been an issue.
In orion third night. First two were fine but the last night balls pull on the on the ring so hard that I didn't get much sleep. Went to pee and all the pressure subsided, I pulled the skin of the balls down the get little bit of relief and it seems to get better. I have ordered larger ring as this one is too tight for me. The cage is bespoke and I haven't manage to be flaccid yet. difficult to say if its too small or too big. I remember from past wearing holy trainer that the first week was the most difficult one and it got easier each night in general. In the end we are locked and some of the painful hardwood night erections should to be expected
