... as you sent me, shows what does seem to be a rather unhealthy foreskin. What is particularly
important, is your explanation that this has developed over the last year or so and that you were
previously able to retract somewhat more if not fully.
The white area corresponds to the inside part of the foreskin between the tip of the penis and the furthest end where at rest the inside folds out on to the outside. This part of the foreskin (all apart from that which is actually over the glans itself) is commonly called the "acroposthion". What is demonstrated is that most
of this actually stretches over the glans when you pull it back, but the tight part in your case is immediately in front of the tip of the glans.
The white discolouration is referred to as "maceration"; the skin is not waterproofed as it should be. Your (slightly confused) reference to some degree of itch very strongly indicates that you do
have a problem with Candida (a yeast, similar to a fungus) and that you should be treating this with a preparation readily available from the pharmacy. You will note that given this problem has been there for some time, you may well need to treat for somewhat longer than usual and probably should take the oral treatment as well
Instructions for use of the cream were explained in this posting
. In the longer term you might want to use the cheaper Zinc and Castor Oil cream to keep this area waterproofed and healthy, particularly as you work on the stretching process.
Since your problem is
caused by a disease process promoting some scarring, it probably would
be useful if you could obtain some of the betamethasone ointment
whose use I most specifically explain on other discussions here. You would necessarily need to use the anti-fungal cream at the same time (but not necessarily applied
at the same times during the day) as the steroid (betamethasone) does
tend to make it easier for the yeast to take hold. Nevertheless, use of the anti-fungal and persistent stretching will
eventually resolve matters, the steroid simply accelerates the process.
