I think perhaps you should point out to what degree you can retract your foreskin when
not erect. If it is indeed your frænulum that is short, it will not permit the foreskin to retract much further when flaccid, than when erect.
If on the other hand, you can retract your foreskin well past the glans when flaccid, but not when erect, then the restriction would be the foreskin
opening itself.
If indeed it is the frænulum that is the restriction and it pulls your glans down severely as you retract (when flaccid), then you do need to stretch it by the technique Jim illustrates. It should actually be pretty easy to do this many times during the day as it only requires one hand and can in many situations be done fully clothed.
I have to giggle at the suggestion of "following it religiously".

People tell me about taking their medication "religiously" and I put it to them that doing it once a week on Sunday morning is nowhere near regular enough!
The point is - we are pretty much always going to tell you to approach the problem by stretching in the first place as
- We know that stretching must work - and can give you the examples such as the "body modification" practices that not only the tribal Africans practiced, but so do the tribal Americans (and British, etc.) in our current day with "flesh tunnels" in ears and such.
- Stretching is applied to structures that are not actually defective but simply have not grown sufficiently; and is virtually guaranteed not to damage nerves or any other function - as surgery always carries at least a risk of doing.
- Effecting the "repair" yourself is a particularly rewarding activity through which you gain "mastery" over your own body and the confidence to approach other problems that you may face.
