Hey Jim, haven't you been reading
my suggestions?
Do I go into too much detail to read?
Yes, I most certainly
do recommend "packing" extra fingers - as many as practical - into the foreskin opening to stretch. The
reason for this is that otherwise, you have to use your arm muscles; that is,
all the various muscles in your arms, to apply the tension, The first step to avoid this problem - and be able to stretch for much longer at a time as we both suggest is important, is to "lean" the two fingers together so that instead of using the arm muscles, you only need to use the muscles which bend the fingers (which are in fact, located in the forearms) to push them apart.
But "packing" in as many extra fingers as will fit, when performing the
later stretching between being able to retract while flaccid, and able to retract when fully erect, allows stretching to be effected using little or no muscular tension at all - almost as convenient as using an external stretching device.
Since a foreskin that will
not retract does not prevent intercourse (the lack of skin mobility and loss of sensation is very much similar to - but not as severe as - being circumcised) because the skin is
so tight that it cannot move back to a position in which enough force is applied to be painful, and since even circumcised men generally feel that they enjoy intercourse perfectly well (knowing no better), it can be argued that there is little need to "correct" the situation. Any "hygiene" concerns are due to other factors, as I have been explaining in
a recent discussion here so they need not be a concern.
Two
good justifications for obtaining full foreskin mobility, are that you literally have a larger
repertoire of sexual options, and that the mobile foreskin enables the so-called "gliding effect" during intercourse where the foreskin may form a "seal" at the vaginal entrance with minimal in-and-out movement while the glans thrusts in and out of the deeper vagina without losing the vaginal lubrication by "stripping" it out. This forms an "insurance" against the woman losing her focus on the act and failing to continue lubricating, which then results in discomfort and complete failure of lubrication in a vicious cycle. You are indeed correct that this is desirable for your future
partner's sake. (

Now, that is indeed a fascinating article (or cascade thereof) that you cite. It certainly
does outline an argument based on
physiological observations (to the extent that you accept their validity, particularly where implied from murine behaviour) as to why persistent exposure to pornography is undesirable (let alone the reasonably obvious psychological consequences) and its "sister" article certainly resonates with my observations of female behaviour. It is not my part to mandate either masturbation or abstinence from it, but thirty days sounds almost like taking it too closely to heart.

Anyway, as to your frænulum, I wonder if you are a little confused - I see
little value (and as described in other discussions, undesirable distortion of the meatus has been suggested) in pulling your foreskin
back to stretch the frænulum, and you seem to imply that you are conflating the stretching of the foreskin opening, with traction on the frænulum. What we illustrate to stretching the frænulum, is to "pinch" the end of the frænulum which merges into the foreskin with forefinger (inside) and thumb (outside). In fact, it is the forefinger of this pair which
actually applies tension to the frænulum, and if the (fore)skin is dry for this purpose, there should be minimal slippage, making it the overall most effective method.
