Warm your tissue so it becomes more stretchable. Once its warm enough you’ll know because you can feel the stretch below your balls when going up and at the base when your going down and down your legs when your going left and right. I wear an extender 3-6 hours a day in hopes that its a good setup but in all honesty it weakens my tissue so that I can move it a lot better. I notice a huge difference when warming up and not warming up and having a stretchy penis compared to one that just wants to turtle as soon as it can.
Edit: Grab behind the head and pull on it in a helicopter type way until you feel which area stretches best and start there then move clockwise on the stretches.
