Here is what little I remember.
1) Very big surprise when bandages removed, as I had not quite been told what "fix" would be done to my wee-wee. In fact at first I did not even understand what had been done, it looked like the tip had been replaced! I don't know how much time it took me to understand.
2) Itching. Perhaps the stitches, or also the scar itself.
3) I think I was made to take sitz baths in water with antiseptic soap but I may be mixing things up.
4) Went to the GP who had advised this surgery, she inspected the scar, pronounced the results very nice, removed a couple stitches that had not dropped, as mom watched. I don't know how many days it happened after surgery was done.
I don't recall friction on clothing. If I recall correctly this surgery had been told during school vacations, so perhaps I was allowed to run half naked in the house, I really don't know.
At that age I would not know what "masturbation" was and I don't recall if I was told not to touch myself there as it healed.
