I also have this problem. When working or running around quickly from place to place I find that I turtle up. For myself, I believe it is a stress response. As soon as Iām home and watching tv or lying in bed it relaxes back to a non-turtled state. Recently, I have switched to Saxx underwear with the pouch in the front and for the past few weeks I have taken a standard hand warmer (the kind that heats up when exposed to air) and dropped it in the pouch. It provides a decent amount of heat and I find it helps to keep my dick relaxed more througout the day. It is a bit of a hassle,however, shifting it around every so often. I have even debated sewing another pouch on the underwear with some old t-shirt material to hold it in place.
