Until recently when using an extender i would just loop over the head and extend. Noticing some light wearing to the skin i decided to pull my foreskin through the extender a bit more and wear it that way for a while. I noticed several big differences. When just the head is looped it makes the head more wrinkly and i feel the stretch deeper like the material in the penis is being stretched... When i pull the foreskin through more the head looks less wrinkly like a few pics ive seen on here (not necessarily good or bad the pic uploader said he had no results.) and the stretch appears to shift to the skin covering the penis rather than in the penis. Is one of these techniques better than the other? Should i switch between both?
