Forced retractions attempts?

No it stays behind the head 100% of the time.

I tried many times to achieve permanent retraction in my teens, but I found that it would keep rolling forward and if I held it back with tape or something it would swell after about 10 hours or so. I knew a boy in early school who was permanently retracted and he had a bulbous ring of skin behind the glans. Did you have to deal with any of that?

Nope I had to deal with none of that.

That sounds more like paraphimosis than a deliberate retraction!
