I've had lig pops before, from pushing downward while erect... but never intentionally and definitely never from PE. Today, doing my stretches, I decided to use some latex gloves I had lying around. During my downward stretches today, I had my very first lig pop while flaccid. In ALL these years of stretching, I've never had that. Quite satisfying. :3 I'll be keeping the latex grip forever now.
