I got the 5 on the hardness scale, and the important thing was getting the skin out of the way near my glans. It takes a while for me to go flaccid again after putting it on. I've been trying to figure out the best direction to wear it. Sometimes when pointing down, it gets like a kink/pinching my shift where it folds. Sometimes at the base the sleev rolls at least once which makes it tighter there. I haven't tried stretching it out over a can yet. Idk if the softer version would feel better or if I need a size in between the 3/4" and 1".
Mainly got this as an ADS and to prevent turtling which hurts to pull myself out again sometimes when having to pee.
