I can only describe my experience. I cleaned the wound daily with wet wipes, and applied the typical tripple antibiotics cream to it in a generous amount. The cream also ensured that the scar tissue stayed rather soft an pliable.
I now do some gentle scar massage, to keep the scar soft, and the scar tissue to a minimum.
Your skin will shrink over time, just be patient, and it will pul pretty close up to the body.
I had a rather atrophied penis prior to the surgery, it did not shrink after it by a measurable amount. I guess it will shrink a little more over time.
At this time I would have a hart time to use a urinal in a bathroom, because I might wet myself more than the urinal! But I am used to pee sitting down, my mother trained my dad and I very well in keeping the bathroom floor clean!
Tucking is not problem anymore for me, because that little bit of skin left, does not cause a male appearance.
