I'm 19 years old & tried to pull down my foreskin for the first time. In unerected state though I was having little bit of pain but was able to pull down my foreskin till the mid way between the head & the base. But while doing it in erected state I was able to expose only half the tip of my penis. Also the foreskin(image link in the end) was like a bottleneck around my shaft when going from unerected state to erected causing a lot of pain. Out of curiosity I tried to masterbate but it was too painful for the tip of my penis. But I saw videos where people pull down their foreskin even in erect state. Also they during sex they feel no pain. Image link(not mine but similar)- i.imgur.com/O5a08.jpg
