Hi, my contribution to this interesting thread for the ones who want to start ...
1) how do you guys masturbate? Uncircumcised guys masturbate by rolling the foreskin up and down, but circumcised guys often just use lube and run over the head too? I also see some circumcised guys in porn masturbate by just jerking behind the glans. Idk, it's just really confusing. Or can I just roll it back but masturbate like an uncircumcised person (pulling the skin forward during masturbation only)?
Before retracting, I used to masturbate by moving the foreskin up and down with 2 fingers on the glans, without ever pulling back. This is a childhood habit that I carried over to the adult world. I kept using this technique initially, but also started exploring the ones I saw used in porn by cut guys. As the glans gradually desensitized, I started jerking the foreskin on the shaft while pulled back. It gave a better buildup because the inner foreskin had retained more sensitivity than the glans. The glans was still the trigger for finishing though, so I usually reverted to covering it just before cumming.
After years of exposure the inner foreskin finally lost sensitivity and thickened, so rubbing it over the glans was not generating anything useful.
I finally settled on a lube method where I stroke the whole penis, and it gives a good orgasm even if it is definitely less "sharp" than the ones when I was still covered, but creates deep sensation.
So you see the masturbation technique in my case had to evolve as my penis changed. You have to adapt.
2) I have also heard of stories which says some guys roll back for a certain period of time. Then the foreskin gets so tight that they end up having to circumcise? That sounds really scary. Can someone advise on this? I do know for a fact that the foreskin will adjust to the size it is being wrapped around. The foreskin will contract if it is pulled back, since it is not stretched by the size of the glans, and it will also get shorter, from some stories and anecdotes that say that the skin naturally stays back after a long time. But this forced circumcision from the blood flow being restricted and skin getting too right really scares me, and this is where my biggest concern comes about.
This has not happened to me. In fact, the puckered end of the foreskin has dilated from being on the shaft for so long. My prepuce used to be very snug-fitting, this is no longer the case now. If I cover, the meatus will be well exposed whereas I sported a little "elephant trunk" before. I wonder if the looser fit of the foreskin did not contribute to the loss of usefulness for wanking.
3) I have seen some photos where the glans look really flaky as progress pics. Are those just glans in the midst of hardening, and the flaky skin will fall off and it will look normal after that?
This has never happened to me. What happened is that the glans went through many textures over the years, before stabilizing to a pink soft state. In the first years it went through a discolored and unhealthy corpse-like tint, before turning grey-blue. The healthy pink color came much later.
4) is it true that pulling back can aid in the head getting bigger since there isn't the foreskin to restrict it from "growing"?
I think not, at least it didn't happen to me ! However since the foreskin is so lax, it does retract fully and painlessly far up the shaft now. Erections and sex are more comfortable.
5) is the desensitisation permanent? If I roll it forward after an extended period of time, will the sensitivity come back?
That's the $1000 question. It depends how long you've been exposed, I guess. Me, after 10 years if I did a one-week break, absolutely nothing changed. I suspect it would take months and possibly more, as one member recently alluded to. The funny thing is I don't want to roll forward ever again, even though I have memories of higher sensation. I also suspect there have been drastic changes in my glans and inner foreskin which I'm not sure can be undone. After all, it took almost 1 year until the pain of being exposed 24/7 finally receded, in my case. That took it toll, no doubt.
