First of all I want to thank you for a very good and informative forum with lots of competent answers to questions about a matter which the doctors of today are strangely uninformed about! Now forgive me if this becomes a bit long :P.
I´m a 21 year old boy who have never been able to retract the foreskin fully while erect, but since I´ve always functioned perfectly while masturbating and while having sex I never saw this as a problem. When my ex started to take the pill and we started having sex without a condom some problems arised with pain and the foreskin almost getting stuck below the glans which of course were not pleasant. Some cracks begin to appear in my foreskin at times which bled and were quite annoying.
I started researching the matter and stupidly the younger me regarded the first thing I read as truth, one must/should be able to pull the foreskin all the way down below the glans! I started doing some serious (not the good kind) stretching with of course even more cracking as a result, and now this white ring which really tightened the foreskin had formed and I could expose even less than before. The pain while having sex was also getting worse.
After several months I decided to see a doctor and after I got referred to a urologist he told me that this white ring was scarring due to the foresking bursting and prescribed dermovat along with some light stretching (this actually worked pretty decent) but warned me that there was a 50 percent chance I would have to do circumcision. Since I really do not want to have my foreskin removed I started googling even more and stumbled upon this site and read almost every page. I have been doing the excercises as prescibed and some small improvement have been shown.
However, after reading through the pages I have a suspicion that my white ring actually might be yeast and not scarring. I am attaching some picture and am hopeful that someone with more experience will take the time to look at the pictures and give me their opinion.
