Different case studies of phimosis (a tight foreskin). Mostly taken from network54 phimosis forum. See right panel for link to my other blog about my theory of how masturbation can cause phimosis.
I did try stretching with creams but no rings, didn't make much of a difference, doc said there's less chance due to my age being 35 and also there was quite a bit of scar tissue due to previously tearing it a few times when attempting to have sex. This scar tissue is not stretchable.
Editor Note: seems to have white patches indicating lichen sclerosus.
