Yes, and no. Yes, if you want to retain that extra 20% sensitivity. No, if you're pursuing PE like a madman for gains. The frenulum was always my Achilles Heel. Once it was cut, healed, and primed, I was able to push even harder without the sore pains from it. Now, the only pains are from the stretched ligs, penile muscle, and sensitive glans from a 24-hr ADS. I could never use more than 4-hrs at a time with the traction/stretcher in the past because of the frenulum. The pain was excruciating. Hanging weights with it beyond 5lbs was a nightmare beyond 5 minutes. LM-wannabe, can't go past 3 minutes. Now, 24-hr ADS is nothing.
