No, just through the build up of pressure caused by ballooning
You really should read that long thread he mentioned. In fact, I started a thread on Dr. Lin (the guru of “ballooning”) even earlier. I’m convinced that Lin is a snake oil fraud. He peddles all types of magic pills and he makes outlandish claims like ballooning can increase your size by some phenomenal % (can’t remember the exact figures).
He also, by the way, blasts jelqing - which I believe is THE single most effective tool in the PE arsenal (for the vast majority of guys). Probably because he can’t make a penny off you jelqing - but his pills ain’t cheap!
He’s also not a medical doctor, or even a trained medical professional of any type (nurse, therapist, etc.). He’s something like a marine biologist who did a lot of work with seismic waves, or some shit. What that has to do with PE, I haven’t a clue (but he always refers to himself as DOCTOR Lin).
I do believe that his ballooning/edging techniques can help you to achieve a rock-hard erection, and quickly. I have experiment with his massaging techniques at the base. But if you already have normal, healthy erections, I don’t believe that any amount of ballooning will increase your size. For gains, PE is the only to go.
