Yes, I do believe we have covered most of this fairly well in the past.
The advice regarding smegma and the advice regarding sensitivity are effectively the same - indeed they are intimately connected! Insofar as the smegma is relatively firm, then it has to some extent been providing a sort of "shell" over the glans (or at least those parts that it covered), acting such as to spread out any movement over a wider area of the glans. Same force acting over a wider area = less pressure
(engineering principle), so the glans has been protected by the smegma as well as the foreskin itself.
On the other hand, insofar as the smegma is soft and greasy, it has been providing lubrication to the glans, which indeed is the natural and appropriate state for it - to be lubricated as it also is during comfortable intercourse.
Being lubricated, it is not subject to abrasion as it might be from touch with a dry hand - it is by no means surprising that this might be unpleasant, but it is after all, a decidedly unnatural
state of affairs begging the question: why
do you need to touch the glans without its natural covering and lubrication - either that of the foreskin (obviously, if you have been previously unable to retract your foreskin, you certainly have been having erections, so you have a foreskin "dimensioned" to cover your erect penis), or a woman's vagina?
Now as regards a purported tendency for the smegma to attract infection, which appears to motivate, or perhaps "excuse" the desire to clear this stuff away; you must ask: "How long has it been there, causing no trouble at all?" What's the difference now that you are retracting your foreskin?
There are people who will assert that bacteria breed under the foreskin (which is actually correct, just as they do on every other square millimetre of your skin) and that "nasty" bacteria are even more likely to multiply there. Well, as you realise, the smegma has obviously been there for years if not your whole life, any bacteria that might have been able to get in there would surely have set up home (and indeed, they have) so - it can't be much of a problem, can it?
In short, it's not a problem, so try not to make it a problem by any form of over-zealous attempts at imagined "cleaning" (such as the use of soap). Wash it with water, what will come off, will, and what won't will continue to serve as a temporary covering and indeed, a protection for your glans. I daresay you haven't taken a look yet, at the corresponding area of a young lady either - it might be very
A couple of hints about smegma - if you wish to loosen it, use oil (some sort of emollient safe to use elsewhere on the body or mouth - given that it resembles the mouth). And - yes, it does smell (because there are bacteria living in it for one thing), again, just like the corresponding part of a young lady does, and a similar smell. Within reason, a quite attractive smell (considering similar secretions from animals are the base of many perfumes). If too strong, washing will almost all of the time, deal with it - for both sexes.
I seem to recall (can't see it yet) that I have dealt with the matter of fraenuloplasty in reply to the thread immediately below. Suffice it to say that "sauce for the goose, is sauce for the gander" or what is good for the foreskin applies identically to the fraenulum. While a fraenuloplasty causes nowhere near as much damage
as a circumcision of any sort, you necessarily lose the satisfaction of "mastery" of your body.
Regarding my "project", let me reiterate that the resource I lack is more than anything, the time
that such an enterprise would require. As much time as I can spare (indeed, far more
than I can sensibly commit) I give as advice here.
