More to the point, beware
reading too much nonsense about scarring.
Do you
realise that
surgery causes scarring? You do not have a "frænuloplasty" to
avoid scarring, you have one to
cause scarring. Try not to confuse yourself - and
do try and avoid the "fetish" sites for this very reason.

There is
no reason to use any form of "cream" on a healing area except where
excess scarring (Keloid) is anticipated, where it is not an "antiseptic" or "antibiotic" but a
steroid ointment - precisely as I discuss in other references here.
It is
not accepted surgical practice to use anything on a wound other than
very gentle cleaning with soap and water - or as it relates to the genitals, warm water
only without soap, to clean away any blood and serum which might favour infection. If scabbing is excessive, petroleum jelly ("Vaseline®") is traditionally used to prevent dressings sticking.
It seems your frænulum was too short. OK,
because it was too short (and/ or you were doing something that was pretty silly at the time anyway), it tore. Having torn, it is now by definition
longer or looser and you want it to be loose, so you want to be stretching it
while it heals
so that it heals - in the looser state. If wounds in this area failed to heal up (promptly), humankind (especially women) would be in a sorry state.
Oh yes, the loose tag - as much as it matters anyway - will probably shrink away. Loose bits of skin are pretty much part of the genitals anyway (have you taken a good look at your girlfriend?) and I do think it is a bit much to argue in terms of "cosmetics" in this regard.
I do
not actually think the frænulum is that important anyway. Its midline location suggests it has little sensation in itself (though the adjacent areas certainly
are sensitive) and I believe its
main contribution is to convey the movement of the foreskin to the rather sensitive area of the urethral meatus. If torn/ cut, this effect may indeed be reduced, but I doubt it matters much.
I am sure you are
deliberating greatly on it, but I fail to accept it as
debilitating.

You need to read a
lot of the discussions here.
