That sounds like the joys of puberty and your body finally finishing growing.
In my case there definitely was a change. On my childhood penis there was just enough skin to cover the whole head without any overhand.
Today even in forward position only part of my head is covered. (see: attached image)
Yet, i guess it was mostly puberty that made me "outgrow" my foreskin. I started retracting a lot earlier without any huge difference until then.
I would say there still was some change afterwards, allowing me to stay retracted much longer finally. But compared to the boost that puberty gave me it was rather minimal if any.
