Even though my skin tends to stay back unaided I thought I'd give the latex glue method a try.
I found that the moisture between the two layers of foreskin caused the glue to lose its stickiness and disintegrate.
I'm sorry you had this problem. Like all retraction methods, some work better for some people than for others. However, sometimes it also takes some trial and error before you have success with a method. I would note that in the way that I've described this method, there should be no point wherein there is skin-to-skin contact. The shaft skin should be entirely coated by the liquid latex, and so when the wrinkles are formed, there should be latex in between every point of contact between the wrinkles. Moisture could still accumulate between the skin and the latex, I suppose, but I have not experienced this problem when I do it. I've definitely experienced moist hands after wearing rubber gloves for an extended period, so it makes sense that this could happen. I'm not sure why it doesn't happen for me on my penis. Perhaps the liquid latex, when applied directly to the skin, may seal the skin pores, reducing perspiration, like an antiperspirant deodorant. Also, when I think about the moisture which accumulates inside rubber gloves, it seems to me that most of it is condensation, not sweat. Perhaps because the liquid latex is applied directly to the skin of the penis and seals it, with no air gap to encourage condensation, this sort of moisture accumulation can be largely avoided, if done properly. However, bear in mind that the latex won't last forever, no matter what you do. It will eventually detach and come apart. This is also true of tape when using the tape method.
