Dexterity with external hip rotation is everything! With most stretches you should think active not passively manipulating a loose limb. The hard part with dexterity in the beginning is the concept of moving a limb in a unique / new direction without the use of other limbs. I'd start by trying to actively widen your hips. lay on your back with knees bent and feet up and try to widen your hips as you bring your knees / direct your knees towards your chest. Usualy being somewhat explosive tied with your breathing makes a huge difference. If the explosive movement feels good with an inhail then definitely do this on your back. If you like to do it on the exhale and this exerciese feels awkward on your back then try it on your knees in a crouch / fetal type position while staying very centered. Once you've gotten the hang of widening your hips, add the concept of "winding" as well. Make sure your hips are still spreading just as wide but simultaneously wind them in the "rubber gaurd" direction. Most likely your legs will barely rotate if at all but you'll feel the muscles / ligaments being worked. Then when you grab the leg it will be assisting this active motion and not torking on your knee. This will probably take a lot of experimenting to find what fits you best and it might even be a new variation that suits how you like to move. here's a link to an exerciese that you should do before and after your other stretches (it's for people with hyper extended knees due to flexability) as a precaution.

There is such thing as healthy knee flexability and it is also used to treat injuries. here's a youtube link for that.
