I have so many years large testes. last year or so it seems to have gotten bigger to the size of maybe a small grapefruit for both of them combined. regardless the second symptom I have gotten was that my penis would actually shrink and literally disappear into the sack when not aroused(I'm around 7 to 8 in arrives, so I don't think it's a size issue this only started happening about a year ago). Much like on a very cold day. Then Last week I noticed there has been a feeling of like a burn ring around the shaft. much like if you were to masturbate, and wrap your finger and some on one spot, that's the part that feels uncomfortable. I'm wondering if that is a results of the folds of the penis backing into the sack, And I'm wondering if that is because the folds are rubbing on my shorts. The other thing I noticed twice is that there is a dimple underneath the skin about an inch from the base of the shaft. No pain, it's more like a BB size. do I have possibly a prostate issue and or an STD? Never had an STD in my life, and currently I experience no pain whatsoever other than the fact of the ring around the base. There is no discoloration just a feeling of sing uncomfortable. Again, I'm wondering if it's just the folds exposed to the shorts rubbing on it as the head of the penis really doesn't come out anymore. Unless I'm aroused. I'm sure this all sounds confusing so please ask questions. I basically have two issues and I'm curious if they're both related to each other or separate issue.
