Actually, what I am suggesting is that the adhesion as such - if it is only at the corona - the rim at the back of the glans - should not be too much of a worry.
Hitherto, you have not been pulling at the adhesion simply because - you couldn't! If your foreskin will not pull back easily, there is no tension on the adhesion to separate it. If you stretch the tight ring that has prevented the foreskin pulling back, then whatever else you do - sexual activity including masturbation, and simply making a point of pulling it back fully whenever you pee - will be pulling the adhesion apart and it may
simply free itself over a period of time - as would be the normal process in childhood.
There is a "rule" regarding separating an adhesion if it causes any bleeding - having done so you must
make sure by regular separation, that it does not re-attach as if it does so it will tend to heal more firmly. This is why I give the advice above - it is better that separation occurs by regular activity in tiny stages.
It is remotely possible that some degree of inflammation has occurred earlier at the normal time of separation and that the adhesion has re-formed as a more permanent attachment, perhaps because such inflammation caused one to at least temporarily, stop the manipulation that is normally responsible for achieving separation.
It is common if not universal in young boys for the foreskin to separate before the opening of the foreskin is large enough to permit retraction. This results in spontaneous "ballooning" of the foreskin on urination (which is sadly often used by ignorant or mendacious doctors as a basis for recommending circumcision), but in fact the ballooning itself (and particularly if deliberately enhanced), as well as the playful stretching of the foreskin to extreme length by the child, actually facilitates the separation and is therefore, entirely desirable.
In fact, inflammation and/ or infection are quite unlikely
in the presence of a tight foreskin since the tightness obstructs anything getting into
the preputial space and urine regularly flushes out anything that does. The main bugbear in this case is actually the use of soap (and even worse, detergent such as "bubble bath") which can insinuate itself into this space and persist to cause irritation.
I trust that you are actually comparing the appearance of your corona to pictures of normal
penes such as those on foreskin.org
. My strict suggestion is - deal with the tight foreskin (and frænulum) first, and then
you may be in a better position to sort out any adhesions. And if you are separating adhesions and causing trauma, it might be useful to have some Zinc and Castor Oil (with no
popular brand names, no "hype") to apply to raw areas to soothe, protect and avoid re-attachment.
