I've posted my story about phimosis earlier in here, but I don't mind typing it out again...
When I was around 7 years old, I had a consult with the school doctor. Just a regular check-up like you get around that age.
Of course, this also meant a genital examination, during which, my foreskin would not budge at all, despite the doc's firm, but still gentle attempts.
In stead of being scheduled for a circumcision straight away, something that is, or was common in the US, I believe, he instructed my mom, who was also there, to have me practice with retracting in a warm bath for a while, and make a follow-up appointment to check on proceedings.
Thankfully, my attempts to retract while in a warm bath paid off, and I got to keep my precious foreskin 😃
Even now, roughly 40 years later. my foreskin is still tight. It won't slide over the glans by itself when erect. But that's how I love it.
When I just retract it partially, and keep it halfway over my glans, the skin is wonderfully tight and sensitive. Doing circles over it with a finger is a very nice sensation.
I absolutely love my foreskin being played with 😃
