Okay, every says when they get hard the forkskin comes back, and the head is exposed..Not in my case. I'm still doing the stretching, and I finally got the skin back while hard by pushing it down, and it worked, but i got up and moved and it went back over the head. I couldnt do it again, because I felt like it was going to snap. How does the forskin stay in place, when hard?
Tight Forskin, pulling back..
When it's a bit looser after more stretching it may be more inclined to stay back, but if it doesn't, don't worry. So long as it can move freely when you're hard, that's fine.
The frenulum (web of skin under the head) wants to pull the foreskin forward to cover the head, while the shape of the head (glans) with the ridge part is designed to keep the foreskin back when erect (clever design, eh? ). In theory, when the penis is flaccid, the foreskin will always automatically be pulled forward by the frenulum unless you hold it back. When erect, the foreskin may or may not retract to expose the head on its own (depends how long the foreskin is), but when you pull it back when erect, it will typically stay behind the ridge of the head (corona) until pushed forward, or the erection goes down, then it will slide back over the head again. If your frenulum is very tight, it will always pull the foreskin over the head, even when erect. It doesn't really matter though, as long as you can retract your foreskin to fully expose the head without pain.
