Thanks guys. Fg, check your PM :)
Zowee, for how long have you done this until you have reached your goal?
Neandertal, firegoat is right, the frenulum should not break during masturbation, unless you totally lack common sense and treat your little friend with absolutely no mercy
Full foreskin pull back is my goal (without having to pull manually and cause tension in the frenulum). I forgot to mention it becomes thin, red and it causes discomfort in the lower glans area (where it attaches).
I will check another doctor’s opinion, don’t fully trust doctors. Thanks a lot guys, looking forward to read more advice/experiences. Best wishes. I.D.
