Given that a device has to be both comfortable to wear out and about and to sleep in and it is generally accepted that a device that allows little room to grow is better for sleeping in, how small is too small? My device fits me in a way that I touch the end when standing, or if I am at my smallest I might be 1-3mm from the end and has a decent amount of room around him. When I am erect I fill everything, obviously. However when I sleep, due to my normal position, on my right side, my penis retracts in the cage (due to be anchored deep in the pelvis) which opens up approx 5-10mm of space that isn't there when standing. So is it better to get a device that compresses your cock slightly during normal daily activities so that there is less room at night; after all a flaccid penis is very flexible. If so, what is the amount of compression that is ok before a device is too small?
