I'm 21 and through online medium I found out I had phimosis. I could not retract my foreskin at all. But i read about auto-circumcision and started to practice it. It basically was a daily routine to try and pull the foreskin backwards for 4-5 minutes everyday without applying excessive force. After 2-3 weeks of practicing that (yesterday), while taking a hot shower, I pulled it back completely. It was not that much painful. And I had pulled it back before but this time, the foreskin stayed retracted. Worst thing, I decided to masturbate to get used to it. It was fine. Until today morning, I see my foreskin has swollen. My searches online concludes either paraphimosis or a natural occurring. Should I be worried? What if it is paraphmosis? Or is it just a part of the routine?
