Hi and welcome to the journey !
1) My glans is already too dry, it has wrinkles and the surface is hard. Should I keep it better moisturised or is it okay to achieve better results?
Some may go for the super-dry look, that was not for me. My take is: take care of your glans and moisturize when needed. It is not the dryness, it is the thickness ... and that doesn't come overnight.
2) On the forum, multiple times, “glans peeling” is mentioned. Does this happen to everyone or is there another method that tells you your progress (level of keratinization)? (/ Again how does the dried out skin affect peeling?)
Personally I never had glans peeling. Even in the beginning.
3) How much time does my glans need to change the texture/sensitivity with this level of consistency? (Smell is already gone, sensitivity is lover but that has to do with the glans being dried out).
It's difficult to remember exactly, but in in my case I had a first change at about 2 weeks. The wetness stopped and the texture was more velvety.
However, I started with a very child-like glans, very thin membrane, and it took me 4 months (repeated twice) to get a stable texture. I think the skin cells have a long cycle anyway, so it took me some time to build those extra layers.
Good luck in your endeavours !
